Performance reviews refer to a process in which an employee's job performance is evaluated and assessed by their supervisor or manager. The purpose of these evaluations is to provide feedback on strengths, areas for improvement, and overall job performance. This information can be used by the employee to develop new skills, improve upon existing ones, and achieve career goals. Additionally, it provides the employer with insight into how well employees are performing in their roles, which can help inform decisions about promotions, raises, or other opportunities for professional development. Overall, performance reviews aim to enhance employee productivity, job satisfaction, and retention within an organization.
