Summary:
Shift work has increasingly become a prevalent employment model, particularly within the service sector. However, its implications for employee health and well-being remain understudied. This thesis aimed to explore the impacts of shift work on perceived sleep quality, general health, and stress levels among service sector employees in Greece. Utilizing a cross-sectional design, the study employed the Pittsburgh Sleep Quality Index, the Depression Anxiety Stress Scale, and the General Health Questionnaire to survey a sample of 153 employees in retail, coffee shops and restaurants and in telephone service. The sample consists of men and women aged 18-64 who work in shifts from 1 month to over 10 years. The findings highlighted a significant correlation between years of shift work and perceived sleep quality (r = 0,212, p = 0,009), της, general health status (r = 0,237, p = 0,003), and stress (r = 0,286, p = 0,000). Specifically, increased years of shift work were associated with poorer sleep quality and elevated stress levels. Also, the results showed that the dimension of stress (sig = 0.001), self-confidence (sig. = 0.043) and sleep quality (sig. = 0.009) are affected by years of shift work. These insights contribute to the growing body of literature on occupational health, underscoring the need for systemic interventions to support shift workers' well-being.
