Colleagues are understood as people who work in the same position, have similar job content or on a related chain of operations in the organization. According to Alemi (2014), colleagues are people who share feelings, knowledge, and interests in their daily work. Colleagues are one of the factors affecting job satisfaction. The colleague factor is understood in this topic as people in the same company who have regular work relationships, care about and exchange with each other, and often contact each other, so the colleague relationship also affects overall job satisfaction.

3- Neutral
4- Agree
5- Strongly agree
The table usually includes 2 parts: The part stating the content, and the part stating the assessments according to each content; with this scale, the respondent must indicate a choice according to the suggestions presented in the table.
