Final answer:
Performance appraisals provide employees and supervisors with guidelines for measuring performance, including the use of a 360-degree appraisal system for a comprehensive review. These appraisals are crucial for reinforcing workplace culture, setting expectations, and documenting performance for future reference.
Step-by-step explanation:
Performance appraisals promote the consistent handling of contacts and provide employees and supervisors with specific guidelines that they can use when measuring performance. These appraisals often involve a structured process, including documented evaluations and face-to-face meetings. Such meetings allow supervisors to express any concerns regarding an employee's performance, highlight good performance practices, and discuss rewards or consequences based on the appraisal's outcomes.
Appraisals may utilize a 360-degree performance appraisal system, where an employee's performance is rated not just by supervisors but also by peers, direct reports, and sometimes customers. This system aims to give a multifaceted perspective on performance, encouraging employee improvement through self-reflection or training. Furthermore, it aids supervisors in making informed decisions about the employee's role and compensation. Performance appraisals play a critical role in establishing workplace culture, ensuring safety, setting clear expectations, providing meaningful feedback, and maintaining a record that can support future decisions regarding employee tenure.
