Final answer:
A 360-degree feedback system gives employees informational power over their bosses by enabling access to a wide range of evaluations from various sources.
Step-by-step explanation:
A 360-degree feedback system provides employees with a form of informational power over their bosses. This type of feedback system collects performance evaluations from a variety of sources, including supervisors, peers, subordinates, and sometimes even customers. Such a comprehensive system empowers employees by giving them access to a wider range of perceptions about their performance. It differs from expert, referent, and legitimate power, as it's based on the ability to access and share information, rather than on expertise, admiration, or formal authority.
