1. Introduction
During the epidemic, construction sites were considered to be places where the virus spread rapidly [
1]. There were many workers at the construction site, including directors, engineer, supervisor, administrator, technical staff and worker. This study refers to all the categories listed above as construction site workers. Many workers at this construction site are at risk of COVID-19 infection [
2]. Social distancing policies, personal protective equipment, and video conferencing have all changed worksite operations [
3,
4].
During the pandemic, construction workers at the primary site faced mounting fears, insecurities, job burnout, and insomnia. Insomnia is characterized by interrupted sleep, difficulty falling asleep, and poor sleep quality, which negatively affects normal body functions and health and in turn affects daily life routines [
5,
6]. Insomnia can be caused by stress, anxiety, and traumatic events [
7]. Studies have found that stressors related to work, family, and health—including work overload and lack of support—are the main causes of insomnia; more recently, COVID-19 anxiety has also been confirmed as a cause [
8]. The current study explored whether job burnout and insecurity have an impact on insomnia among workers.
Many studies have confirmed the occurrence of severe sleep disorders during the COVID-19 pandemic [
9,
10]. Severe insomnia led to subsequent physical and psychological problems among frontline workers [
11]. Many researchers have identified hyperarousal as a major cause of insomnia [
12]. Insomnia is mostly caused by stressful situations [
13]; when individuals are unable to cope with the challenges of stressful events, it can be difficult to fall asleep. The COVID-19 outbreak inevitably also contributed to job burnout and insomnia among construction site workers.
Job burnout is a symptom of prolonged work stress [
14]. It can cause emotional exhaustion, depersonalization, and diminished personal accomplishment. Emotional exhaustion causes employees to feel unmotivated to work [
15]. Depersonalization occurs when an individual is blamed for problems at work and therefore feels negative emotions and attitudes [
16]. Diminished personal accomplishment is a negative evaluation of one’s ability to perform tasks and interact with people, along with feelings of dissatisfaction and unhappiness [
17]. Employees who suffer from job burnout are prone to anxiety and depression [
18]. The sudden onset of COVID-19 affected many aspects of the economy, and it impacted many part-time and full-time workers [
8]. Although most natural disasters are short-lived, the COVID-19 pandemic lasted 2–3 years, and during that time, one out of every five frontline workers was confirmed to have experienced job burnout [
19].
Zhang found that group support reduced job burnout for psychological counselors [
20]. In a study of healthcare workers, Zhao et al. found that social support enhanced workers’ self-efficacy, which in turn reduced job burnout [
21]. A nursing study in South Korea found that social support was beneficial for frontline personnel to face the hardships of the pandemic [
22]. Multiple studies have noted that frontline workers faced anxiety, depression, and burnout during the pandemic [
23]. Job demands require employees to be committed to their work, which creates psychological and physical stress [
24].
From the perspective of the conservation of resources theory, individuals who have social support resources are more likely to effectively cope with stress and reduce burnout [
25]. Conversely, when individuals lack personal, social, and material resources, it is more difficult for them to cope with stress [
26]. According to the conservation of resources theory, individuals will strive to acquire and conserve the physical and psychological resources they value [
27]. The loss of these valuable resources can cause individuals to feel stressed. Economic crises, natural disasters, and the spread of disease can all cause individuals to feel a sense of loss in terms of resources.
According to the job demand–resources model, job demands are job requirements that tend to create job stress for workers, whereas job resources are the provision of job skills and resources that help to reduce job burnout [
28]. The job demand–resources model stipulates that when job demands exceed job resources, employees are prone to burnout and health problems [
29].
The outbreak of the pandemic in 2019 led to changes in working hours and workloads for many frontline workers, in addition to contributing to job burnout [
30]. Furthermore, the lockdown policy during the pandemic containment period disrupted social support for workers. Some studies have demonstrated that social support during outbreaks can reduce job burnout [
31]; conversely, a lack of social support can cause anxiety, depression, and insomnia in workers [
32].
Many studies have emphasized the importance of personal protective equipment during a pandemic. A study by Gallop et al. revealed that the greatest fear among caregivers for HIV patients was that of being infected [
33]. During the Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) outbreaks, the WHO found that failure to ensure the proper use of personal protective equipment contributed to the spread of the diseases [
34]. Inadequate personal protective equipment also led to a high risk of infection during the 2014 Ebola virus disease (EVD) outbreak [
35]. Therefore, the lack of personal protective equipment increased the fear of COVID-19 among frontline workers [
36]. Frontline workers were also concerned about transmission to their families as a result of their work [
37]. Construction workers also faced fears of COVID-19 infection while working at construction sites.
Job insecurity is the feeling of powerlessness to maintain a stable job in dangerous situations [
38]. Job insecurity is recognized as a source of stress in the work environment, and it has a negative impact on the physical and mental health of workers [
39]. The COVID-19 pandemic created a sense of uncertainty and insecurity about future construction site work. In addition to feeding insecurities about future job stability, the COVID-19 outbreak necessitated increased safety behavior in the workplace, i.e., the need for workers to comply with protocols in the face of risky situations [
40]. Being asked to conduct temperature checks, wear masks, and practice social distancing at the worksite during the pandemic were all causes of stress for workers. At the same time, high environmental stress, work overload, uncertainty, and excessive demands are known to affect the safety behavior of workers [
41].
Job security is the degree to which an existing job is stable or consistently threatened [
42]. Individuals’ feelings of uncertainty about job security can increase their stress levels [
43]. The perception of job insecurity can lead to insomnia, and self-regulatory resource theory suggests that insomnia affects self-recovery [
44]. When individuals lack sufficient resources to cope with hazardous environments, they can develop sleep disorders and sleep impairments. Economic depression, travel restrictions, and material shortages caused by the COVID-19 pandemic all affected individuals and negatively impacted the work and life aspects of construction site workers.
The main contribution of the current study was the incorporation of Riggs’ formalism into the COVID-19 study of construction site workers. When there is a discrepancy between pandemic prevention regulations and their implementation, it can lead to anxiety and job burnout among workers. Riggs described the formalism of administrative agencies mainly in the context of developing countries [
45]. His criterion of using American society as a diffracted society has been challenged by scholars who argue that, although the United States is the benchmark for developed and industrialized societies, it is a mistake to claim that American society is totally devoid of formalism [
46]. Some scholars have argued that prismatic societies exist not only in underdeveloped countries, but are also common in countries with different levels of development [
46]. Taiwan is also gradually emerging from its status as a developing country; however, due to the influence of Asian and Chinese cultures in the past, studies have also confirmed the existence of formalism in Taiwan [
47,
48,
49].
Formalism as proposed by Riggs involves ritualistic methods, lack of authorization, and centralization. Ritualistic methods create a gap between the norms of law and their effective implementation, along with a gap between administrative norms and realities. The absence of objective evaluation standards and the lack of pressure on civil servants to implement programs allow formalism to develop easily [
45]. Riggs therefore concluded that there is a difference between administrative ritualistic procedures and the rationalistic procedures of developed countries. Ritualistic procedures are not implemented in practice, and thus leave a gap between administrative requirements and actual implementation performance. When epidemic prevention measures are not implemented in practice, workers’ psychological exhaustion and burnout increase. In countries with higher levels of formalism, the lack of shared values at the administrative level and inconsistency between governmental and social values creates a gap between administrative planning and people's expectations [
50]. Workers’ job burnout therefore increases due to dissatisfaction with epidemic prevention measures at work.
5. Discussion
This study used path coefficient analysis of structural equation modeling (SEM) to verify all research hypotheses. First, this study confirms that insufficient protective equipment will increase COVID-19 fear among construction site workers. The problem of insufficient personal protective equipment has arisen during the COVID-19, Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) epidemics. These diseases all have the characteristics of sudden appearance, rapid spread, and lack of vaccines and drugs. These characteristics can easily cause COVID-19 fear among construction site workers when they lack adequate personal protective equipment [
55,
57].
This study confirms that social support can reduce job burnout among construction site workers. From the perspective of conservation of resources theory, social support can help construction site workers cope with work stress and burnout [
25]. The job demand–resources model regards job resources as a kind of job skills and resources, which can reduce job burnout caused by job demand [
29]. Construction site workers during the epidemic face many work demands and new work processes, and they need more social support to reduce work burnout.
COVID-19 fear among construction site workers has caused physical and psychological burdens on construction site workers [
77]. COVID-19 fear among construction site workers further contributes to burnout [
78]. Insufficient personal protective equipment at construction sites creates greater fear and burnout among construction site workers [
82].
Natural disasters and epidemics require government agencies to make quick decisions and effectively implement policy plans. However, institutions in developing countries will make people feel that policies and implementation are inconsistent. Agencies in developing countries often view compliance with work processes as the primary goal, rather than using work processes as a tool to achieve policy goals [
84]. Pathological behaviors with high formalism include: overemphasis on process, red tape, lack of concern for public interests, and fear of innovation [
90]. Construction site workers feel that the failure to implement epidemic prevention policies will increase their emotional exhaustion.
The high infection and mortality rates of COVID-19 infection can create a sense of fear among construction site workers [
76]. The epidemic has caused factory closures, economic stagnation, and remote work, all of which have increased job insecurity among construction site workers [
94]. Reductions in work and financial pressure can create perceptions of job insecurity among workers on the job site.
Long-term emotional and physical exhaustion among construction site workers can easily lead to insomnia [
103]. Shift changes and increased epidemic prevention work during the epidemic can easily cause burnout and insomnia among construction site workers. This study confirms that job insecurity of construction site workers affects their insomnia. Self-regulatory resource theory advocates that sleep allows individuals to restore energy. Insomnia can lead to more accidents and injuries among construction site workers [
109]. It can be seen that the job insecurity caused by the epidemic has a negative impact on the safety of construction site workers.
