1. Introduction
The United Nations Sustainable Development Goals, particularly on quality education (Goal 4), aspire to equal access for all to quality tertiary education. Such access is intertwined by the concerted efforts of both teachers and students in a fostering and safe environment. However, the ongoing COVID-19 pandemic has remarkably disrupted people’s way of life, including the educational sector, impacting over 60% of the world’s student population [
1], aside from its adverse impacts on the education workforce. Educational organizations swiftly established alternative learning modalities that limited in-person classes from the basic to the tertiary levels. Higher education institutions (HEIs) adopt a flexible learning system (FLS) to avoid and reduce the dangers of infections in the academic community. Several studies (e.g., [
2]) espoused the practicality of the FLS amid the COVID-19 pandemic. Flexible learning affords several options for personalizing the learning experience depending on the learners’ unique needs and preferences [
3]. This approach allows students to choose their learning path while meeting formal learning objectives. In addition, it encourages students’ independence and inventiveness [
4].
Implementing FLS entails the integration of technology using e-learning resources, facilities, and equipment, including but not limited to laptops, smartphones, tablets, and others. A recent study by Santiago et al. [
5] revealed that cellular mobile applications were the frequently used educational device and e-learning resources that support FLS. On the other hand, online learning platforms, both for synchronous and asynchronous classes, have become popular, especially among HEIs. Meanwhile, Google classroom has made it one of the leading extensively used online learning platforms for synchronous classes intended to promote learnability [
6]. Kumar [
7] claimed that the popularity of Google classroom is associated with its characteristics being cost-effective, easily accessible, and user-friendly. It improves student engagement, enhances group dynamics, allows for self-paced learning, information accessibility, and exchanging files between teachers and students and makes online learning faster [
8]. Other emerging online learning platforms that were very popular for teaching and learning activities during the pandemic include Canvas, Microsoft Teams, and Edmodo. On the other hand, Northey et al. [
9] examined the use of Facebook to facilitate asynchronous learning opportunities complementary to face-to-face interactions. Ramadan [
10] finds Facebook to be an effective pedagogical and promising educational tool for conducting teaching and learning processes. Under remote learning during the pandemic, Barrot [
11] recently claimed that students who use Facebook-based e-portfolio had outperformed those from the conventional portfolio group. Nevertheless, integrating technology and learning domains provides teachers and institutions with more freedom to use time and space in innovative ways that cater to the needs and interests of their students [
12].
Despite the promising benefits of the flexible learning modality, several issues have spurred its implementation. In addition, among many reasons, educators may be relatively open or closed in their views about a flexible learning environment. Mishra et al. [
13] point out that some faculty members who are not technologically knowledgeable will find adopting this approach challenging. In an FLS, teachers who are used to traditional teaching delivery must embrace technology despite their lack of technological literacy [
14]. Teachers are compelled to rethink the changes in their teaching roles, the learning content, students’ degree of attention, interest, passion, internet connectivity, and pedagogical knowledge [
4,
15,
16].
Various factors are linked to amplified turnover rates due to technological advancements and the trend toward flexible learning in education. Among these were issues with student conduct, a lack of faculty input in educational decision-making, insufficient administrative support for the institution, and low remuneration [
17]. Several studies in the USA have suggested that teachers’ decisions about their jobs are influenced by their salaries [
18]. Environmental, individual, and organizational factors can impact teacher turnover [
19]. Li and Yao [
20] found that burnout is a significant predictor of teachers’ intention to leave the profession, while workload and stress significantly correlated with it. Moreover, teachers express concern about how to make students more visible on Internet-delivered courses; how to personalize instruction and student connection; how to involve students in extra interactive learning; how to differentiate and pace learning activities, and how to advance more effective strategies for learning, evaluation, and reflection and take care of health and safety of their students [
21]. Likewise, teachers’ view of the flexible learning environment stresses the importance of a good fit between the educational program, professional learning development, and the school design to create a thriving learning environment [
16]. Additionally, in the case of developing economies such as the Philippines, IT infrastructure is one of the identified challenges which could hinder the smooth implementation of technology-driven instruction [
22].
These challenges could affect the teacher’s intention to teach in an FLS, which is associated with turnover intention [
23]—an employee’s final decision or action before leaving the organization [
24]. Tett and Meyer [
25] initially described turnover intention as a conscious and purposeful desire to quit the organization. A stream of the literature reveals various factors, including theoretical models, associated with turnover intentions [
26,
27]. One of the occupations with the highest turnover rates is teaching, with some insights offered in previous studies [
28]. Since it requires direct interaction with essential stakeholders, teaching is a profession that provides high levels of emotional demands [
28]. Emotional needs are associated with detrimental effects such as teacher burnout, job discontent, and diminished zeal [
29]. Lee [
30] found a clear correlation between burnout and teachers’ intention to leave the profession. In addition, teachers find the job to be highly stressful due to student misbehaviors and disciplinary issues. Aloe et al. [
31] found a link between student behavior and teacher turnover. Additionally, studies (e.g., Hanushek et al. [
32]) show that geographical locations influence working circumstances, school and student characteristics, and teacher mobility. As a result, demanding schools typically experience greater levels of teacher turnover [
33,
34]. On the other hand, social support has been shown to interact with workplace stress factors in predicting the willingness to resign among various employees [
35], including teachers [
17,
36]. Surprisingly, the findings revealed that teachers who felt they had received inadequate administrative support were more than twice as likely to leave their current position. However, due to technological advancements and the trend toward flexible learning in education, especially during the COVID-19 pandemic, the turnover rates of teachers have been amplified.
There are various models used to explain turnover intentions, including the Self-Determination Theory (SDT) [
37], the Theory of Reasoned Action (TRA) [
38], and the Theory of Planned Behavior (TPB) [
39]. See Kim and Fernandez [
40], Gagné and Deci [
37], and Zhao et al. [
41] for the SDT, TRA, and TPB applications. SDT offers insights into how employee empowerment positively impacts job satisfaction; thus, it can be a ground for employees not to leave their job [
40]. It explores variables including employee empowerment, job satisfaction, and turnover intention. However, these constructs are weak in determining the volitional and non-volitional factors in leaving the teaching profession. For instance, to increase confidence and competence among teachers, they must first believe in their capacity to perform associated tasks (attitude), which is considered volitional behavior. Non-volitional factors refer to those behaviors following external factors, such as teachers having confidence because others think they are capable of performing the tasks. On the other hand, TRA includes only attitude, subjective norms, and turnover intention as variables. Distinct from TPB, which predicts non-volitional behaviors by incorporating perceptions of control over the performance of the behavior as an additional predictor, TRA restricts itself to volitional behavior [
39,
42]. Behaviors requiring skills, resources, and opportunities not freely available are not considered to be within the domain of applicability of the TRA [
43,
44] but are relevant in modeling turnover intentions. As an extension of the TRA, TPB expands the model’s scope by incorporating perceived behavioral control (PBC) as an additional construct to address the non-volitional factors associated with behaviors. This makes the TPB more fitting in modeling turnover intentions, as evidenced in prior studies [
41].
Despite the popularity of TPB in turnover intention studies, using technologies to support FLS requires a more elaborate model that captures teachers’ confidence in the tech-savvy environment. Along this line, teachers’ confidence tends to influence their view or attitude (volitional factors) on how well they can perform a specific task (i.e., learning activities in an FLS), as well as how others view them (non-volitional factors) in successfully executing the task. Others’ knowledge of such confidence impacts their view on how teachers can perform those tasks. Popularly, in the domain literature, teachers’ confidence is highly associated with self-efficacy and digital nativity (e.g., [
41,
45,
46]). On the other hand, the current literature emphasizes the role of job satisfaction and organizational commitment on teachers’ attitudes [
47], which may have different variations among teachers than in other workforce groups. Job satisfaction promotes a positive workplace environment and enhances employee enthusiasm [
48]. Consequently, when teachers are satisfied with their jobs, it tends to affect their behavior in performing a given task [
49]. Moreover, organizational commitment denotes employees’ dedication to voluntarily rendering extra services beyond their specified scope of work to attain organizational goals [
50]. The presence of commitment among employees impacts their attitude in performing required tasks, particularly in an FLS where more efforts are needed to become familiar with the technology-driven environment.
Thus, this study extends the TPB by incorporating self-efficacy and digital nativity in its primary constructs to better explain teachers’ turnover intention, given that FLS is the primary mode of teaching and learning. In addition, consistent with several studies in the literature, job satisfaction and organizational commitment are considered antecedents of attitude within the context of TPB. Following the notion and some empirical evidence [
51] that age affects the intention to work in a technology-focused environment, the proposed model integrates the role of age in teachers’ turnover intentions. Some studies argue that younger workers are more adaptive to new technologies than older ones [
52]. With a mix of young and old generations among faculties in HEIs, such an argument may hold ground. This extended TPB model is deemed more relevant in capturing idiosyncrasies associated with the presence of technologies to support FLS. Cross-sectional empirical validation of such a proposed extended TPB model is implemented in the faculties of Philippine HEIs with partial least squares-structural equation modeling (PLS-SEM). The insights of the proposed model would advance our understanding of the factors affecting teachers’ turnover intention, which could be inputted into the design of human resource management interventions in HEIs amidst implementing the FLS in teaching and learning processes.

5. Discussions
This section presents the salient features of the PLS-SEM analysis and how these results can be applied to the current discussions of teachers’ turnover intentions attributed to the implementation of FLS. The findings of our empirical study suggest that self-efficacy directly impacts subjective norms (H2) and perceived behavioral control (H3), and these agree with previous findings (e.g., [
27]). Teachers’ beliefs on their capabilities in FLS would influence others on their views on the capacity to implement FLS. Consequently, it would improve one’s thinking of how others perceive such potentiality, especially those who matter to them. For instance, people observing teachers with strong convictions about their competence in using associated technologies in FLS would positively view their competence in performing necessary tasks. Similarly, higher self-efficacy improves behavioral control [
93,
94]. Teachers with strong beliefs about their capabilities to manage students in virtual environments tend to have greater control in performing initiatives that promote self-paced learning among students in FLS. As a case in point, if teachers believe that they can control the potential disruptive behavior of students and motivate those who show a lack of interest in schoolwork, they will tend to pursue teaching as they would find themselves effective in teaching via the FLS modality.
Despite growing with and speaking the language of digital technologies, results revealed that these characteristics do not affect teachers’ attitudes (H4) toward FLS. This finding contradicts the insights of Gretter and Yadav [
98], suggesting a positive correlation between attitude and media literacy. Even with highly proficient teachers with technologies, especially for information gathering and social communication purposes, their attitude towards FLS does not depend on this competency. With the opportunity to gather in small select groups and teachers’ perception of the adequacy of equipment as part of the indicators of the attitude construct, they are deemed independent of teachers’ level of digital nativity. This finding implies that despite teachers’ proficiency in FLS technologies, the absence of adequate supportive equipment may be detrimental to implementing FLS. Furthermore, the characteristic of FLS that promotes self-paced learning among students may be less associated with digital nativity. Meanwhile, digital nativity directly impacts subjective norms (H5). This implies that the belief that teachers could teach in an FLS by the people they consider important affects teachers’ view of themselves regarding the easy manipulation of digital technologies. This insight is consistent with the findings of Milutinović [
99]. The result of H6 is more straightforward as digital natives are more likely comfortable with the technology demands of FLS. Teachers with higher levels of digital nativity could design effective teaching-learning materials such as podcasts, interactive videos, asynchronous activities, and gamification platforms in learning and promote authentic assessment tools of student performance.
The results of this work establish the significant influence of job satisfaction on attitude (H7). It supports an established stream of literature on the topic (e.g., [
140]). It implies that teachers are far more likely to have a positive attitude toward their intention to teach in FLS if they achieve contentment or fulfillment with their jobs, which may consequently impact their intention to quit teaching. Moreover, organizational commitment directly influences attitude (H8). This result supports the findings of Straatmann et al. [
107] and Yousef [
108]. Teachers with a strong commitment to the organization, who work hard to achieve the desired organizational goals and put in a great deal of effort beyond what is normally expected from them, tend to have a positive outlook on teaching FLS. As the requirements of FLS are disruptive to the status quo, the criticality of change-supportive commitment among teachers becomes imperative, as highlighted by Straatmann et al. [
107]. Learning educational technologies promotes appropriate pedagogical practices, revitalizes assessment tools, and reinvents classroom management practices.
Hypotheses H9, H10, and H11 represent the traditional relationships of the TPB model, which are supported by various studies in the literature [
41,
141]. From these hypotheses, attitude (H9), subjective norms (H10), and perceived behavioral control (H11) affect the intention of teachers to teach in FLS, as suggested by an R
2 = 0.609, with perceived behavioral control as the strongest predictor of the intention with
f2 = 0.369. The teachers’ perspective regarding the adequacy of supportive learning technologies, professional networking, and their morale in implementing FLS positively relates to their intention to teach in such a modality. When these provisions are limited, a substantial portion of their intention to teach in FLS would be diminished. In addition, the intention to teach is significantly affected by social pressures, particularly with people who have a direct influence on teachers (e.g., deans, supervisors, colleagues, and family members). Finally, relevant resources, knowledge, and skills enhance the ability to control better the teaching-learning process, which is considered highly critical in predicting the intention to teach in FLS. This insight contributes significantly to the domain literature by highlighting perceived behavioral control as positively associated with teaching and, consequently, the intention to leave the profession within the context of FLS modality in teaching. This might be attributed to the disruptive demands of FLS, particularly with the advent of technologies and the necessary skills associated with it, which are not yet considered mainstream among teachers, especially in the case study. It suggests that teachers must gain the required control, reflected by the availability of technologies, capacity-building initiatives, and supportive organization, in effectively carrying out the requirements of FLS before establishing the intention to teach. Limited resources and support may compel them to re-evaluate their intention to teach in the FLS modality.
When age is introduced as a moderating variable to the relationship between attitude, subjective norms, and perceived behavioral control, this study finds such an effect of age insignificant. This is brought about by the possible migration of non-digital natives (i.e., highly associated with age) to adapt to the skills needed for implementing FLS. Lastly, the PLS-SEM analysis determines the relationship between the intention to teach in FLS and the intention to leave the teaching profession. The findings show a significant parameter estimate of −0.194. It supports the agenda that their intention to quit the teaching job can be predicted by their intention to teach under an FLS modality. Thus, when an FLS mode is imposed in an HEI, a critical mass of human resources with a low perception of FLS may look for another university which is not forcing FLS or move to another non-teaching job. Administrators may subscribe to the insights of this study to enhance teachers’ intention to adopt the FLS mode of the teaching-learning process to retain valuable human resources. Nevertheless, the model proposed and validated in this study successfully integrates the TPB to examine turnover intentions in the teaching workforce. The 11 supported hypothesized paths are an affirmation of the strength of the proposed model. These results indicate that future works may modify antecedent variables, extend to different workforce groups, and incorporate existing relevant models. For example, there are levels of digital nativity among generations. A deeper understanding of age-groups taken in different periods is needed. Moreover, one can investigate when and in what context the instructors can feel more confident with their actions. This idea can be extended with Bandura’s [
142] dimensions of self-efficacy beliefs, most especially on mastery experiences and vicarious experiences. Another possibly deeper analysis can be viewed with different dimensions of organizational commitment (e.g., creativity and continuance commitment, goal commitment). The high explanatory power of the endogenous variables in the model (i.e., attitude and intention to teach in FLS) suggests the model’s strength.
6. Practical Insights
This section provides practical insights based on the critical findings of the study that might be useful to higher education stakeholders and university leaders. The high explanatory power of the proposed extended TPB constructs on the intention to teach in FLS, and the consequent turnover intention of teachers becomes an essential takeaway for educational leaders. Designing initiatives that support the insights of the proposed model would be useful since the attitude, behavioral support, and control of the teachers, who are considered the main actors in implementing FLS, are hypothetically supported. The contributory aspect of attitude, intention, and ability to perform the tasks in teaching must be aligned with the policy directions to the design elements of an FLS. For example, since FLS supports personalized learning for students, it is beneficial to provide support and empower the teachers to develop learning spaces or personalized learning dashboards within a curricular offering. Along this line, it should be noted that the presence of idiosyncrasies may need HEIs to design their FLS. This addresses various learning needs that may be specific to a particular case.
On the other hand, as the emerging literature suggests, job satisfaction and organizational commitment factors remain intangible factors that university leaders must consider in improving teachers’ attitudes toward implementing FLS. Together with self-efficacy, these factors explain about 57% of the total variation of the attitude construct. In this study, teachers expect more support to properly implement a flexible learning environment, especially on the infrastructure. In most developing countries, such as the Philippines, infrastructure that supports information technology (IT) and Internet connectivity is a pressing challenge in conducting remote and online teaching. For instance, the Philippine regulatory commission has released a marching order to sustain flexible learning in higher education, highlighting the retrofit of facilities in HEIs. There are limited technology-enhanced experiences with poor Internet connectivity, and factors such as systems interactivity, infrastructure interoperability, and user interface designs of the learning platforms cannot be evaluated with certainty. The strength of the IT infrastructure can also shape teachers’ efficacy, especially on pedagogical consequences to carry out the needs of FLS. Consequently, these factors impact teachers’ turnover intention in light of the FLS implementation.
The antecedent variables (i.e., self-efficacy and digital nativity) have shown importance in explaining the TPB factors (i.e., attitude, subjective norms, and perceived behavioral control) toward implementing FLS, except for self-efficacy on attitude. Emerging results consistently imply the importance of digital nativity in the current learning environment, especially in view of FLS. Notably, this work reveals no moderating effect of age on the intention to teach in FLS. Thus, policy directions must consider digital nativity and self-efficacy for all age groups to address the difficulty in the FLS implementation. For instance, capability training of teachers on the delivery of topics in FLS shall be continually administered. These training programs must be carefully designed, emphasizing appropriate technologies and support tools, such as interactive remote learning materials, asynchronous activities, and game-based learning platforms, that are consistent with the characteristics of FLS. Aside from designing appropriate training programs, the fast-changing upgrades of technology must be considered to anticipate new challenges and sustain the implementation of a flexible learning environment.
Finally, the proposed structural model comprising the intention to teach in FLS inversely varies with the intention of teachers to leave the teaching profession. Although with a small percentage of explanatory power (3.5%), the relationship is significant and holding all other factors constant, the intention to teach in FLS is a predictor of turnover intention. It has been posited in the emerging literature that the post-pandemic new normal emphasizes the continuity of flexible learning [
143]. Since FLS involves both online and face-to-face, it is practical to articulate the learning management systems, update online content, and provide new learning designs for face-to-face instruction. In this manner, support for FLS can be converted to enhanced digital literacy, better job satisfaction, higher self-efficacy, and improved organizational commitment. When appropriate measures to address these factors are in place, teachers are likely to enhance their intention to teach in FLS, and consequently, turnover intentions become minimal.
7. Conclusions and Future Works
This work proposes and validates an empirical model that examines teachers’ turnover intentions in HEIs regarding the implementation of FLS, especially during the post-pandemic. To explain teachers’ attitudes, the TPB model has been extended to determine the variations of the intention to teach in FLS with self-efficacy and digital nativity as antecedent variables, along with job satisfaction and organizational commitment. This extended model is linked to the turnover intention of teachers and is confirmed in a case study of 417 teacher participants using PLS-SEM. Furthermore, the moderating effect of age is investigated due to the notion that FLS is highly dependent on educational technologies. The proposed model generates 12 hypotheses, and the empirical case supports 11 of them. The model provides high explanatory powers in its endogenous variables.
Four essential contributions are put forward in the study. First, the TPB constructs logically explain the part and overall variations of the intention to teach in FLS by about 60.9%, confirming the significant role of self-efficacy and digital nativity on the TPB constructs, with the perceived behavioral control construct contributing the highest effect (f2 = 0.369). Thus, it is imperative that policy directions focus on initiatives that improve teachers’ self-efficacy and digital nativity linked to enhanced perceived behavioral control. Secondly, the variations in the teachers’ attitudes toward FLS explain self-efficacy, job satisfaction, and organizational commitment. The literature considers these intangible factors as the foundation of attitudinal characteristics. Specifically, the support system on the desire to implement the FLS is critical in improving efficacy beliefs, satisfaction, and commitment. The call to support strategies is more pronounced in the case country, especially on the existing challenges of IT infrastructure and Internet connectivity. The third notable finding is that age has no moderating effect on the intention to teach in FLS, affirming that there is no need to realign support strategies to different age groups. This indicates that the older age group is catching up with the younger generation of teachers in terms of developing digital tools to implement the FLS. Lastly, there is a negative relationship between the intention to teach and the intention to leave the teaching profession. This inverse relationship supports the notion that teachers’ intention to teach in FLS is a predictor of turnover intention. These findings benefit education stakeholders, especially university leaders, knowing that the turnover intention can be managed if appropriate measures to support FLS are designed to enhance teachers’ intention to teach.
Similar to other existing studies in this field, this study has some limitations. One is the need to have a closer look at the self-efficacy construct and a deeper understanding of different support dimensions and other facilitating conditions relevant to carrying out the FLS. Another potential constraint can be attributed to the limited geographical location of the study participants due to the observance of COVID-19 protocols during the data collection (i.e., online survey). Thus, it is suggested that different population groups (i.e., different cultural aspects, comparing countries) should be analyzed to validate and provide a more comprehensive report of the current study. Furthermore, some constructs might have inherent interdependencies with other constructs, which would make the structural model highly complex. The use of PLS-SEM could not effectively handle these complex models. Cognitive modelling tools based on graph theory, including decision-making trial and evaluation laboratory, interpretive structural modelling, and fuzzy cognitive mapping, can be implemented to uncover salient information about the intertwined relationships of the constructs.
The overall theoretical significance of the study leads to specific insights for future works. Among those, we suggest three compelling directions: (1) a deeper understanding of the variations of the extended TPB model in different periods and institution types (i.e., public or private), (2) self-efficacy can be extended with Bandura’s [
142] dimensions on mastery experiences and vicarious experiences, and (3) analysis can be viewed with different dimensions of organizational commitment (e.g., creativity, continuance commitment, and goal commitment).
