An employee of a firm or organization who is elected to serve as the first-line representative of unionized worker.

Union Steward (aka Shop Steward) is the title of an official position within the organizational hierarchy of a labor union. Its uniqueness lies in the fact that rank-and-file members of the union hold this position voluntarily (through democratic election by fellow workers or sometimes by appointment of a higher union body) while maintaining their role as an employee of the firm. As a result. the Union Steward becomes a significant link and conduit of information between the union leadership and rank-and-file workers.
