The sample number in the study is 328 and the questionnaire questions were applied only to the people involved in the shift working system. Parametric or Non-Parametric analyses will be performed according to the distribution of the data obtained. In parametric analyses, t test and Anova will be used. Mann Whitney U and Kruskal Wallis tests will be performed in Non-Parametric analyses. In addition, Cronbach's alpha test will be performed to measure the reliability of the data and explanatory and confirmatory factor analyses will be performed to determine the factor structures of the scales used. With the data obtained as a result of the study, it has been comprehensively discussed whether there is a causal link between shift working and occupational accidents, near misses and occupational diseases occurring in the enterprise.
