Abstract:

The modern labour market is characterised by dynamic changes and a growing need to ensure round-the-clock availability of services, which results in an intensification of shift work. Although this model of work is crucial for the functioning of many sectors of the economy, it poses significant health and psychological challenges, particularly in terms of circadian rhythm regulation and sleep quality. Sleep, a fundamental element of the body's regeneration, plays an important role in maintaining physiological and mental balance. Sleep disorders resulting from shift work can lead to a deterioration in well-being, reduced professional efficiency, health problems, decreased concentration and an increased risk of errors and accidents in the workplace.

The aim of the study is to analyse the relationship between shift work and employees' sleeping habits, and to identify the health, psychological and professional consequences of sleep disturbances. The results of scientific research in the fields of occupational medicine, psychology and chronobiology will be presented, as well as the results of surveys and industry analyses. Based on these, practical recommendations will be formulated for personnel management and support for employees working in a shift system, aimed at minimising the negative effects of shift work and improving the quality of professional and private life. The work aims to provide knowledge for both the scientific community and management practitioners, indicating optimal organisational strategies that promote the health, well-being and efficiency of employees.
