Final answer:
Mike's stress is likely caused by high job demands, a lack of decision-making control, and role ambiguity, leading to job strain as defined by occupational stress theorists Karasek & Theorell.
Step-by-step explanation:
Mike's stress level can probably be explained by a combination of excessive job demands, work overload, and a lack of control over decision making in his job as a clerk. Both Mike and Josh have been working for the same duration and are on equal pay, which indicates that status and salary may not be the contributing factors to Mike's stress. The discussion around who gets to make decisions about what parts to order suggests a scenario where both are dealing with role ambiguity and conflict in work relationships. Mike's stress is likely due to the job strain caused by high demands paired with low discretion, as per the theory by Karasek & Theorell (1990). This is exacerbated by the lack of supervisory support, as humorously depicted in the Office Space movie clip.
Mike's stress level can probably be explained by job strain, which is a work situation that combines excessive job demands and workload with little discretion in decision making or job control. This can cause stress and dissatisfaction in the workplace. Many jobs involve heavy workloads and little job control, which can lead to job strain and increased stress levels.
