This study aims to examine the opinions of Religious Culture and Ethics Teachers (RCET) on mobbing in the workplace. The research focuses on RCET’s definition of mobbing, the reasons for mobbing, the results of mobbing, and the suggestions of RCET to prevent mobbing. This study used the phenomenological method, one of the qualitative research methods. The data obtained from the interview forms were analyzed by the content analysis method. The findings were organized and presented under themes and sub-themes. The study group of the research was determined by a systematic sampling technique, one of the probability-based sampling methods. The study group of the research consisted of 35 RCET working in the middle schools of Mersin central districts in the 2023-2024 academic years. Findings revealed that participants defined the concept of mobbing using terms such as pressure, violence, distress, attack, discomfort, implication, and exposure. It was found that participants expressed reasons for mobbing, such as establishing dominance, jealousy, inadequacy, and conflict of interest. It was determined that participants indicated the results of mobbing, such as asynchrony, inefficiency, failure, resignation, reluctance, and fear-anxiety. The participants suggested solutions such as support, awareness activities, relationships and communication, knowledge of legislation and laws, equality, responsibility, trust, problem identification, solution orientation, and providing education.
