A union representative, union steward, or shop steward is an employee of an organization or company who represents and defends the interests of their fellow employees as a trades/labour union member and official. 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. Above the steward level, a bargaining unit chair is typically elected to coordinate union activities across the unit, lead formal negotiations, and represent the unit in dealings with management and the union’s executive leadership.
