In the research, the relationship between the dark leadership perception, work engagement, psychological contract and organizational structure perceptions of white-collar employees of five-star hotels in Istanbul, Ankara and Antalya was analysed. In this regard, data was collected from 402 white-collar hotel employees through surveys. Frequency distribution analyses, reliability analyses, confirmatory factor analyses, correlation analysis, mediator and moderator effect analyzes were conducted.
