Labor unions in the United States have the fundamental right to represent their members before an employer. On behalf of workers, unions negotiate contracts with employers—setting wages, hours, and working conditions—and represent members in grievance procedures. In addition, the National Labor Relations Act (NLRA) provides workers with important protections when they are being investigated by an employer for possible discipline. These protections are called Weingarten rights, named for one of two Supreme Court cases, decided concurrently, that established this important right.
