Please answer question #2

Facts The Screen Actors Guild (SAG) is a labor union that represents performers in the entertainment industry. Lakeside Productions, an entertainment production company, signed a collective bargaining agreement with SAG, making SAG the exclusive union for performers that Lakeside hired for its productions. The collective bargaining agreement contained a standard union security clause which provided that any performer who worked for Lakeside must be a member of SAG. Naomi Marquez, a part-time actress, auditioned for a one-line role in a TV episode to be filmed by Lakeside and won the part. When Marquez did not pay the $500 membership fee to SAG, Lakeside hired another actress for the part. Marquez sued SAG and Lakeside, alleging that the union security clause was unlawful. 1.
