A Players' Union is an organization that represents the interests of professional athletes in various sports. Its primary role is to negotiate collective bargaining agreements, which cover issues like salaries, working conditions, and benefits. By uniting players, the union ensures that their voices are heard and that they have a say in important decisions affecting their careers. These unions also provide support in disputes between players and teams, offering legal assistance and guidance. Notable examples include the National Football League Players Association (NFLPA) and the Major League Baseball Players Association (MLBPA), which advocate for the rights and welfare of their members.
