Off the job training involves removing employees from their normal work environment to learn new skills through various techniques. Role playing allows participants to simulate real work situations and practice management skills. Sensitivity training helps individuals become more aware of their own behaviors and how they impact others. Case studies present actual business situations for trainees to analyze and make decisions on. While off the job training has advantages like more learning time and assessment opportunities, it also has disadvantages such as high costs and not directly linking to job skills.
