Which concept refers to others' perceptions of an employee's job responsibilities?

The concept that refers to others' perceptions of an employee's job responsibilities is role expectation. Role expectations encompass the beliefs and assumptions that colleagues, supervisors, and the organization at large hold regarding what a particular job entails and how the employee should perform their duties. This is crucial because it helps shape the work environment, influences interpersonal relationships, and guides the employee’s actions within their role by setting a standard that they are expected to meet.

Role expectation is distinct from factors like role definition, which pertains to the specific formal enumerations of job duties and responsibilities, and role identity, which refers to how an individual sees themselves in relation to their role. Role implementation involves the actions an individual takes in performing their job, but it does not encapsulate how others view those responsibilities. Thus, role expectation is the most appropriate term as it captures the perceptions held by others.
