Marcia is an employee of the State Department of Child Welfare. She is part of a bargaining unit that has voted to be represented by a union. The union negotiates with the state concerning the workers' wages and terms and conditions of employment, and it also engages in political activity supportive of policies that it considers to be in the interest of workers. Marcia disagrees with the union's political stances, so she does not wish to join the union. May she be forced to join the union or contribute union dues as a condition of employment? Group of answer choices She may not be forced to join the union or pay any fee. She may not be forced to join the union and to pay a "shop fee" (her share of the union's collective-bargaining costs), but she may not be forced to pay for the union's political activity. She may be forced to join the union and pay dues, because the bargaining unit voted for the union and otherwise the union would not be able to represent the interests of the entire bargaining unit. She may not be forced to join the union, but she may be forced to pay union dues
