The article discusses the challenges and factors influencing organizational commitment which has influence on the staff turnover in aviation organizations. The studies reveal that organizational commitment plays a huge role in a relationship between an individual and organization. If an employee’s organizational commitment is high, it is scientifically proven that his or her intention to change the organization is low. In the Lithuanian aviation sector, the impact of organizational commitment has not yet been assessed in any research. Also, the studies did not yet consider the different groups of aviation employees and the differences in their perceptions of organizational commitment. The aim of this article is to investigate the level of organizational commitment in the Lithuanian aviation sector among employees’ groups and to compare the results with the data from other surveys. The study reveals that organizational commitment is different between managerial and non-managerial staff. These results are useful for a broader analysis, which can be conducted in assessing the impact of organizational commitment between different groups of employees and to propose a model that reduces the difference in organizational commitment between different groups of employees. The observation of organizational commitment level can be made among different groups of employees.
