Based on the results of researcher observations at one of the companies in Indonesia, in addition to cases of embezzlement of company money, there are several other misconduct behaviour s that occur. Based on researcher observations as a courier operations supervisor in 2019, misconduct behaviour seems to have become a habit. There were 16 unscrupulous employees with 38 cases of misconduct behaviour that harmed the company financially. This qualitative research process involves important efforts, such as asking questions and procedures, collecting specific data from participants, analysing data inductively from specific themes to general themes, and interpreting the meaning of the data. Researchers will draw meaning based on data analysis that researchers have found by using an inductive style or drawing specific things to the general. The implementation of this research consists of 4 stages, namely the preparation, implementation, data processing and output stages. Misconduct behaviour is caused by frustration from employees due to a reduction in the reward system received. Although it has been conveyed to management, employees feel that their aspirations have never been fulfilled or only considered.
