2.2. Work Domain Path: PC/RC, Job Control, and Well-Being at Work
Job control refers to the degree to which employees feel that their work can be controlled by themselves, and the job characteristics can give employees the freedom of choice. This control includes the ability to control time planning, schedule arrangement, specific process, material allocation and other aspects [
16]. Job control plays an extremely key role in the acquisition of employees' well-being at work [
4]. Through the use of work communication tools, employees can control the progress of work and give feedback anytime and anywhere, which is conducive to improving job control [
2,
7]. However, constant work connectivity forces employees to always be online [
12]. In addition, employees passively respond to the continuous call from remote work [
17], and they can hardly control the frequency and time of passive response [
11], which greatly weakens employees' autonomy over their schedule, working methods and decision-making [
2], that is, their job control is reduced. This contradiction is known as the “empowerment/enslavement ” paradox [
25,
26].
Gong et al. (2024) argue that the key to the “Empowerment/Enslavement” Paradox lies in distinguishing between Personal Connectivity (PC) and Remote Connectivity (RC) [
4]. The modes in which PC and RC alter boundaries differ, which determines the types of interruptions they cause and consequently their differing impacts on job control [
27]. PC induces only internal interruptions within individuals, which make employees feel in control of their own volition, thereby providing a sense of mastery over time and space management [
4]. In contrast, RC constitutes an external interruption that often demands immediate response, characterized by unpredictability and enforceability, disrupting employees' original schedule [
4]. Hence, PC enhances employees' job control, whereas RC diminishes it.
However, when the PC exceeds a certain limit, employees also start to feel less in control of their job. If an employee is immersed in his or her work almost all day, he or she has actually become a "slave" to his or her work [
25], dominated and controlled by the work, and the flexibility and control of his or her work are greatly damaged [
28]. Constant online work can result in employees not being able to make autonomous decisions about work schedules, work methods, decision-making, etc. Employee autonomy at work is diminished [
29]. Therefore, excessive PC will weaken job control. Thus, PC has an inverted U-shaped effect on job control. At low levels of PC, PC enhances employee job control. At high levels of PC, PC will instead weaken employees' job control.
Job control reflects the autonomy of employees in managing boundaries [
16]. This autonomy can provide employees with more choices between work and family domains, and bring positive emotional and psychological resources to employees [
20]. Positive emotions can directly improve employees' well-being at work [
13]. And positive psychological resources can also help employees obtain other resources, reduce emotional exhaustion caused by work requirements consuming work resources [
2], and thus increase employees' well-being at work. A number of existing studies have confirmed that job control can improve well-being at work [
30].To sum up, PC and RC can affect well-being at work by affecting job control. Based on the above discussion, this study proposes the following hypotheses:
H1a. Job control mediates the inverted U-shaped relationship between psychological contract (PC) and job satisfaction. Excessive or insufficient PC hinders employees from attaining job control, thereby reducing job satisfaction. Only a moderate level of PC maximizes employees' job control and subsequently enhances well-being at work.
H1b. Job control mediates the negative impact of role conflict (RC) on well-being at work. An increase in RC weakens employees' job control, consequently diminishing well-being at work.
2.3. Family Domain Paths: PC/RC, Work-to-Home Conflict, and Well-Being at Work
Work-to-home conflict refers to the extent to which individuals perceive that work interferes with their responsibilities and roles in taking on the family and makes their time and energy in the family domain shrink [
31,
32]. Specifically, the work-to-home conflict is divided into three aspects: time conflict, pressure conflict and behavior conflict [
32]. Time conflict refers to the time spent at work that makes it difficult for individuals to participate in family activities and complete family duties. Stress conflict means that work pressure spills over to the family field, and individuals are still psychologically focused on work at home, so that it is difficult to meet family needs. Behavioral conflict is when the behavior that is beneficial for work contradicts the behavior that is expected in the family.
WCBA increases work-to-home conflict from three aspects: time, recovery and conversion. In terms of time, work connectivity is reflected in the fact that employees are still working after work hours, which will occupy the time originally used for family company [
33], thus resulting in time conflict. In terms of recovery, WCBA will hinder employees' psychological detachment [
12,
34], resulting in the compression of employees' normal rest time and the failure to form effective recovery experience [
35]. Over-consumed resources that cannot be replenished in time will lead to insufficient resources [
36], resulting in stress [
37], and thus stress conflicts. In terms of switching, the intermittent nature of WCBA requires individuals to constantly switch between the two domains of home and work [
20]. After work, individuals should always pay attention to the information in work, and the priority of work role is usually higher than that of family [
11]. This can cause individuals to be absent-minded when engaging in family role behaviors [
2,
10]. This behavior, although beneficial for work, fails to meet the expectations of family role behavior [
5], and thus may lead to behavioral conflicts.
More precisely, we argue that RC induces employees to have more work-to-home conflict relative to PC. From the perspective of employees' psychological preparation, employees engaged in PC have spontaneously increased the flexibility of boundary crossing to the work field in advance, and have been psychologically prepared to work from home after work. Employees engaged in RC have difficulty anticipating when job demands will occur and are often asked to respond unprepared [
4]. This difference has three effects: Firstly, employees engaged in PC can arrange the specific time of WCBA in advance, which can buffer the adverse impact of WCBA on the family to a certain extent. But in the same case, RC lacks time autonomy [
28]. Employees need to respond passively to job demands. This leads to more time conflicts [
6]. Secondly, compared with employees engaged in PC, employees engaged in RC are usually not psychologically prepared to face RC and face greater threat of resource loss, so they feel greater work pressure [
4,
37]. This can lead to more stressful conflicts. Thirdly, employees engaged in PCS generally avoid PC interference with important family activities [
37]. However, employees engaged in RC cannot predict when RC will occur, so RC will cause additional behavioral conflicts.
The negative impact of work-to-home conflict on well-being at work has been confirmed by some studies [
2,
38]. From the perspective of time conflict, if individuals often use the time that should be used in the family domain to work, the support of resources from the family domain will be reduced. This will affect the completion of subsequent work and lead to job burnout [
11], which in turn reduces well-being at work. From the perspective of stress conflict, when work stress spills over to the family domain, employees cannot recover the mental energy lost at work at home. This will further lead to increased stress [
6], which will lead to emotional exhaustion in subsequent work [
4], and therefore reduce job happiness. From the perspective of behavioral conflict, if employees often engage in behaviors beneficial to work after work, they cannot meet the behaviors expected by family members. This will affect employees' performance of their family roles and may cause dissatisfaction among family members [
5], which will be transmitted to employees and employees will further transfer such negative emotions to their attitudes toward work [
11]. Therefore, it reduces job happiness.
H2a. Work-to-home conflict mediates the positive relationship between PC (RC) and emotional exhaustion. The increase of PC (RC) will exacerbate work-to-home conflict, thereby diminishing employees' well-being at work.
H2b. Compared to PC, RC leads to a greater extent of work-to-home conflict, ultimately resulting in a more pronounced reduction in well-being at work.
Boundary integration preference refers to the degree of preference of individuals to connect affairs in the work domain to the home domain and minimize the boundary between the two [
23]. Integrators (i.e. employees who prefer to integrate work into their home domain) like to bring the unfinished work to the family after coming home from work, and tend to reduce the boundary between work and family so that work affairs can flow to the family field [
23]. Integrators prefer their work and family boundaries to be highly flexible. Employees with low integration preference prefer to determine strict and impermeable boundaries between the two domains [
6]. WCBA is the penetration of work elements into the home domain, which facilitates boundary integration preferences to continue completing work during off-hours [
39]. This satisfies the preference of employees to work continuously at home[
39]. Therefore, for boundary integration preference, the impact of WCBA on work-to-home conflict is well alleviated [
18]. Employees with a low level of boundary integration preference do not want work matters to disturb their families [
11], and when it happens that work time encroaches on family leisure time, such employees are more likely to destroy their work-family balance and feel higher levels of work-to-home conflict [
14], and the effect of WCBA on work-to-home conflict is strengthened. Therefore, individual boundary integration preferences are able to mitigate WCBA induced the work-to-home conflict.
More precisely, we argue that, relative to RC, relationships in PC-induced work-to-home conflict are affected to a higher degree by individual boundary integration preferences. According to the boundary theory [
20], in addition to individual boundary integration preferences, work-to-home conflict also depends on employees' autonomy in boundary management [
6]. Employees with more autonomy in boundary management perceive less work-to-home conflict [
4]. Employees take the initiative to manage the boundary and have stronger independent choice of boundary management. Therefore, employees engaged in PC have stronger autonomy in boundary management. Therefore, compared with employees engaged in RC, employees engaged in PC have greater autonomy in boundary management. Work-to-home conflict is more easily mitigated by personal boundary integration preferences. Based on this argument, this study proposes the following hypothesis:
H3a. The negative impact of PC (RC) on well-being at work through work-to-home conflict is mitigated by integrators. When integrators’ boundary integration preference is higher, the effect of PC (RC) on work-to-home conflict is weaker, and then the effect on well-being at work is weaker.
H3b. Relative to RC, the relationship "OC→ work-to-home conflict → well-being at work" is more mitigated by individual integration preferences.
According to the hypotheses, this study proposes the theory model (See
Figure 1).
