Background and objectives: This research relies on a combination of variable- and person-centered approaches to help improve our understanding of the dimensionality of job demands by jointly considering employees' global levels of job demands, exposure and their specific levels of exposure to challenge and hindrance demands.
Design and methods: We relied on a sample of 442 workers who completed a questionnaire twice over three months. Our analyses sought to identify the nature of the job demands profiles experienced by these workers, to document the stability of these profiles over time, and to assess their associations with theoretically-relevant outcomes (i.e., work engagement, job boredom, problem-solving pondering, work-related rumination, proactive health behaviors, and sleep quality and quantity). Furthermore, we examined whether these profiles and associations differed as a function of working remotely or onsite.
Results: Five profiles were identified and found to be highly stable over time: Globally Exposed, Not Exposed, Not Exposed but Challenged, Exposed but Not Challenged, and Mixed. These profiles shared clear associations with all outcomes, with the most adaptive outcomes associated with the Exposed but Not Challenged profile, whereas the most detrimental ones were observed in the Mixed profile. However, none of these results differed across employees working onsite and those working remotely.
Conclusions: These findings have theoretical and practical implications regarding the effects of work characteristics on employees' functioning.
