1. Introduction
The Indonesian construction industry has been growing rapidly in recent years due to the government’s focus on infrastructure development. It is a significant industry which contributed about 10.3% to the country’s gross domestic product (GDP) in 2018, making it the second largest construction market in Asia [
1]. The industry employed 4.8 million people in 2010 and the number increased drastically to 8.1 million in 2017, representing about 6.7% of the workforce in Indonesia. This rapid growth is predicted to continue [
2]. Despite its significance, the Indonesian construction industry has a poor occupational health and safety (OHS) performance record. Statistics on the number and rate of accidents in the construction industry are unreliable, but it is estimated that 30% of all occupational accidents in Indonesia occur in the industry [
3]. However, research on OHS in the Indonesian construction industry remains scant and can be divided into two main areas: research which identifies safety risks, influences and consequences; and research which explores the industry’s safety culture and climate.
This paper contributes to the second theme, building on the limited number of previous studies in this area. For example, Sutalaksana and Syaifullah [
4] found that positive safety climate in the Indonesia construction sector positively influences safe behavior because it reduces work pressure and removes barriers to work safely. Andi [
5] determined the level of safety culture in the Indonesian construction industry using six factors, including top management commitment, safety communication, safety rules and procedures, work environment, worker competence, and worker involvement. In high-rise buildings in Indonesia, Irawadi [
6] suggested that safety climate is a predictor of safe behavior and positively influences project performance. Most recently, Machfudiyanto and Latief [
7] have also recently developed a conceptual framework for developing construction safety culture in Indonesia.
While valuable, the problem with this research is that it is fragmented and has sometimes failed to distinguish between the related but distinct concepts of safety culture and safety climate (see for example Andi [
5]). Furthermore, previous research on safety climate in Indonesia has not considered the multilevel nature of safety climate [
8]. Finally, while valuable in highlighting the importance of safety climate as a key variable in safety performance, there is as yet no integrated framework to guide future research and management action in this area. To address this gap in knowledge, this paper aims to develop a safety climate framework for the Indonesian construction industry.
More specifically it aims to do this by exploring three key research questions which have so far gone unanswered:
What is the state of safety climate in the Indonesian construction industry?
What are the strengths and weaknesses of this climate?
What can be done to improve it?
Such research is important because as Lingard et al. [
9], Sunindijo and Zou [
10] and Hecker and Goldenhar [
11] indicate, the development of a safety climate framework could potentially act as an important leading indicator for better safety outcomes in the industry. Furthermore, Andersen et al. [
12] showed that a positive safety climate at both the construction site level and workgroup level was associated with lower rates of self-reported accident, improve safety performance and decreased risk of accidents and injuries.
2. Safety Climate
Safety climate was first defined by Zohar ([
13] p. 96) as “a summary of molar perceptions that employees share about their work environments.” Criticizing the prevailing tendency for managers to blame workers for poor safety, Zohar’s contribution was to reposition arguments around the need for management to improve safety climate, measured using a safety climate survey which explored factors other than the typical safety risks which had dominated safety research until that time. Building on this formative work, many definitions of safety climate have been proposed. For example, Cooper and Phillips ([
14] p. 497) defined safety climate as the “shared employee perceptions of how safety management is being operationalized in the workplace at a particular moment in time”, while more recently, WorkCover Queensland [
15] defined safety climate as “the perceived value placed on safety in an organization at a particular point in time”.
The term safety climate is often used interchangeably with the term safety culture [
16]. Helpful in distinguishing between safety culture and climate is the definition advanced by Health and Safety Executive [
17] which contained three interrelated dimensions of safety culture: behavioral; corporate; and psychological. The behavioral dimension is concerned with what people do within the organization, which includes the safety-related activities, actions, and behaviors exhibited by employees. The corporate dimension is reflected in the organization’s policies, work procedures, management systems, control systems, and communication flows. The psychological dimension of safety culture concerns how people feel about safety and safety management systems and is what is commonly referred to as the safety climate of the organization, showing that safety climate is an integral part of safety culture [
18]. As Moran and Volkweln [
19] note, organizational climate refers to the recurring patterns of behavior, attitudes and feelings that are visibly perceived to characterize life in an organization by its members. When individual perceptions of the impact of a work environment on their well-being (psychological climate) are shared among members of an organization, these collective perceptions represent the organizational safety climate. In contrast, organization culture refers to the deep, stable and invisible patterns of collective values, beliefs, assumptions, norms and expectations on which people’s behavior, attitudes and feelings depends [
20]. Research also shows that safety climate is a multilevel construct with distinct sub-climates operating both vertically and horizontally within different work groups and teams and levels of organization [
9,
21].
Contemporary safety research, within and outside the construction industry, considers safety climate as a valid concept and reliable indicator of OHS performance [
22,
23,
24]. There are numerous benefits of using safety climate as an indicator of safety performance [
16,
25,
26]. First, traditional safety indicators, such as incidence rates, are lagging indicators, measuring the performance of the past based on what has already happened. This limits managers’ ability to proactively manage risks before they arise and their accuracy also depends on the capability and honesty of an organization in reporting incidents. Furthermore, organizations that diligently report and investigate incidents are disadvantaged in comparison to those that are careless in their reporting, making it hard to motivate organizations to accurately report their incident cases [
27]. Safety climate, on the other hand, is a leading indicator of safety performance which is able to identify areas of risk in advance, allowing organizations to proactively improve them. Importantly, the measurement of safety climate in an inherently collaborative process requiring the involvement of employees, which not only utilizes an important source of human and intellectual capital too often neglected in traditional lagging indicators, but in itself, contributes to enhancing safety climate [
16,
25,
26].
In seeking to develop a tool to measure safety climate, there has been a proliferation of research seeking to identify safety climate dimensions. In an early attempt to synthesize and simplify this literature, Guldenmund [
18] suggested that the number of safety climate dimensions can be reduced significantly by relabeling existing dimensions. Zohar and Luria [
21] distinguished between strong and weak safety climate, with strong safety climate being characterized by a high degree of consensus between members about commitment to safety, while weak safety climate are characterized by a low level of consensus. Hecker and Goldenhar [
11] concluded that the major interrelated variables used to identify safety climate in the research literature include; management commitment; employee involvement and/or empowerment; safety communication; safety competence; balance of safety and production; and supervisory and co-worker safety support. They also noted that construction is a highly segmented industry and that efforts to measure and improve safety climate and safety culture may require different strategies for different types of companies, large and small. In later work, Schwatka et al. [
28] review of construction-specific articles that developed and/or measured safety climate, confirmed that researchers commonly define safety climate as perception-based, but that the indicators used to measure safety climate varied widely, with safety policies, procedures, and practices being the most common, followed by general management commitment to safety. Furthermore, they found that safety climate scores were commonly compared between groups (e.g., management and workers, different trades), and often correlated with subjective measures of safety behavior rather than objective measures of safety and health outcomes. The most recent construction research to develop a specific tool to measure safety climate is Zou and Sunindijo [
16] who found that safety climate is generally measured in relation to six key factors: degree of management commitment to health and safety; effectiveness of informal and formal communication between managers and the workforce about health and safety issues; safety policy, rules, and procedures that are perceived as practical, realistic, and appropriate; a supportive environment characterized by safe working conditions and trusting relationships between workers and managers; a workforce that is actively involved in developing health and safety initiatives rather than being passive recipients of safety policy and procedures from the top; and regular training for employees to identify safety risks and perform their works safely.
5. Conclusions
Addressing the paucity of research in construction safety the aim of this paper was to study the nature of safety climate in the Indonesian construction industry, its strengths and weaknesses and what can be done to improve it. The objective was to produce a model of safety climate for further empirical testing and for facilitating safety improvements in the Indonesian construction industry. In recognizing the limitations of our findings in that they were produced within the context of tier-one construction sites, our results point to a moderately healthy safety climate. However, without comparative research in other tiers of the Indonesian construction industry, it is difficult to make definitive judgements in absolute terms. More research in clearly needed to replicate our research in other comparative contexts.
In terms of the strengths and weaknesses of this climate, our research highlights several key issues, particularly around conflicts between production and safety logics, OHS cost trade-offs being made against other competing project priorities, poor safety communication, poor working conditions and acceptance of these as the norm, poor reporting and monitoring practices, poor training and a risky and unsupportive working environment which prevents workers from operating safely.
Our research has also provided new insights. For example, it has highlighted two new OHS climate paradoxes, the first being the contradictions between management words and management practices and the second being the contradictions between concern for OHS and their low sense of personal accountability and empowerment for acting to reduce these risks. Other new insights relate to the low locus of control of our respondents and how this may be related to prevailing Indonesian cultural norms around high levels of collectivism and power distance. Finally, our results also shine a new light on poor OHS policy enforcement and suggests that this is related to problems of policy complexity, practicality, robustness and revisability and potential conflicts between formal and informal OHS norms, practices and procedures.
In advancing theory in this area, our research also points to the potential value of new institutional theory in exploring the problematic interactions between formal and informal OHS normal, practices and procedures we have uncovered. Issues of effective policy design can also be explored in more depth through what would be a new conceptual lens for safety climate research. We also advocate the use of more innovative methods such as ethnography to untangle these issues and suggest that other important avenues for future research include replicating this work on lower-tier construction sites. Our findings also spotlight the need for more research in areas such as modern slavery, the grey informal workers economy and worker wellbeing.
Finally, from a practical perspective, our findings highlight the need for managers and policy makers to develop improved methods of communication around OHS policy, especially engaging with new multimedia technologies. There is also a need to improve OHS training using such technologies, behavior-based and learner-centered approaches. Safety training also need to be more regulated, robust and regular. Managers also need to increase personal accountability for OHS in construction workers through stronger management commitment and leadership, greater worker empowerment and by cultivating more open and no-blame cultures in site. Managers also need to provide a more supportive environment for workers and improve the provision of PPE to enable workers to operate safely coupled with improved monitoring and enforcement regimes. Finally, policy makers and managers need to make OHS regulations and policies less complex, more practical, more robust and more revisable, if they are to be implemented effectively on site.
Our results are reflected in the integrated climate framework in
Figure 1 which organizes our findings and recommendations into project, organizational and industry/national levels. The framework indicates that improving OHS in the Indonesian construction industry cannot be done in isolation but only through the commitment and collaboration of numerous stakeholders across these three levels. This framework when tested and refined in other contexts, could potentially act as an important lead indicator for better safety outcomes in the Indonesian construction industry and its value should also be explored by testing in other industries and international construction industry contexts.
