Communications Workers of America v. Beck, 487 U.S. 735 (1988), is a decision by the United States Supreme Court which held that, in a union security agreement, unions are authorized by statute to collect from non-members only those fees and dues necessary to perform its duties as a collective bargaining representative. The rights identified by the Court in Communications Workers of America v. Beck have since come to be known as "Beck rights," and defining what Beck rights are and how a union must fulfill its duties regarding them is an active area of modern United States labor law.
