What is the meaning of the senority system in the committee?

The seniority system in a committee refers to the practice of granting privileges and influence to members based on their length of service. Typically, longer-serving members are given leadership roles or greater responsibility, reflecting their experience and knowledge. This system can strengthen institutional continuity but may also limit the opportunities for newer members to contribute. It is commonly used in legislative bodies, such as the U.S. Congress, to determine committee chair positions and other important roles.
