The purpose of this paper is to examine the impact of human resource training on the integration and success of organizational change in Greek four and five-star hotels. The literature review has revealed that training is the most important variable for the success of a change management program. Thus, it is essential to examine its impact on the integration and success of a change management program. Hence, the authors conducted quantitative research on a sample of 513 employees who worked in Greek hotels through an electronic questionnaire where the measurement tools of Theriou (2009), Miller (1997), and Zand and Sorenson (1975) were used. The outcome of the research indicated that some of the human resource training dimensions can be significant positive predictors of integration and success of change, while other training dimensions are negative predictors of integration and change. As a result, hotel management should identify the training programs that will have to be applied according to the needs of the employees.
