Abstract

Objective: To analyze the sleep quality of a company’s employees and its implications on quality of life and well-being in the work environment. Method: An exploratory and
descriptive study was conducted in order to quantitatively and qualitatively evaluate, in a cross-sectional manner, the impact of sleep quality on night shift and day shift employees in a company located in Southern Santa Catarina, using scores from the Pittsburgh Sleep Quality Index, Psycap Questionnaire and Brief Pain Inventory. Results: The results revealed that night shift professionals showed significantly higher levels of optimism and overall
psychological capital compared to the morning shift. However, no significant associations were found between shifts and the dimensions of self-efficacy, hope, resilience, pain intensity or interference, nor with sleep quality. Conclusion: Contrary to the initial hypothesis, night shift workers showed better psychological capital and did not report poorer sleep quality — with professionals on the day shift being the most affected in this regard, possibly due to longer working hours and higher cognitive demands. Although the reported pain was mild, continuous monitoring is recommended. Methodological limitations highlight the need for future studies with larger samples and individual variables to deepen the analysis of these relationships.
