Not between strategies historically employed by some unions however now illegal in the United States are: (i) Jurisdictional strikes centered on which the unions will stand for a firm’s staff. (ii) Agency shop contracts forcing the non-union staff to pay ‘agency fees’ to cover costs of collective bargaining through unions. (iii) ‘Sitdown strikes’, in which the striking workers make it not possible for non-striking staff or managers to work as strikers reject to leave the firm’s building. (iv) Closed shop contracts, in which the firms agree to hire just applicants who are already the union members.
