The term "Union Leader" refers to an individual who represents and advocates for the interests of a labor union. These leaders negotiate contracts, address workers' concerns, and work to improve working conditions and wages for their members. They play a crucial role in organizing workers and ensuring their voices are heard in discussions with employers. Union leaders often have a background in labor relations or activism and may hold positions within larger organizations, such as the AFL-CIO or SEIU. Their leadership is essential in fostering solidarity among workers and promoting collective bargaining efforts to achieve fair treatment in the workplace.
