Also, employee participation was the highest factor that influencing employee perception of PMS, followed by employee knowledge and skills, and rating techniques. Overall, each of the factors had a significant relationship with the PMS. This study may assist managers in improving their communication with employees on their work performance. Therefore, this will increase the employee understanding of how they have been assessed and feel that the process is fair.
