Final answer:
The Taft-Hartley Act placed restrictions on unions but did not specifically prohibit supervisors from joining unions; therefore, the statement is false.
Step-by-step explanation:
The statement that the Taft-Hartley Act specifically prohibits a supervisor from joining a union of production and clerical workers is False.
The Taft-Hartley Act passed in 1947, actually restricted many of the powers of unions. One of the provisions of the act eliminated rules mandating that workers join unions. It also banned closed shops and union shops, which required employees to either belong to a union before being hired or join the union as a condition of employment. However, there is no specific prohibition on supervisors joining a union of production and clerical workers.
The Taft-Hartley Act passed over President Truman's veto in 1947, imposed several restrictions on labor unions. The Act's provisions specifically targeted union activities by banning both closed shops and union shops, where employment is contingent upon union membership.
Moreover, it required union leaders to affirm they had no communist affiliations and limited the use of union funds in political campaigns. It did not, however, contain a specific provision about supervisors being barred from joining unions; rather, it focused on eliminating rules that mandated workers—generally—to join unions as a condition of employment. Hence, the statement that the Taft-Hartley Act specifically prohibits supervisors from joining a union of production and clerical workers is False.
