7. Taft-Hartley

Before Congress passed the Taft–Hartley Act over President Harry S. Truman's veto in 1947, unions and employers covered by the National Labor Relations Act could lawfully agree to a closed shop, in which employees at unionized workplaces must be members of the union as a condition of employment. Before the Taft-Hartley amendments, an employee who ceased being a member of the union for whatever reason, from failure to pay dues to expulsion from the union as an internal disciplinary punishment, could also be fired even if the employee did not violate any of the employer's rules.

The Taft–Hartley Act outlawed the closed shop. The union shop rule, which required all new employees to join the union after a minimum period after their hire, is also illegal. Under the law, it is illegal for any employer to force an employee to join a union.

A similar arrangement to the union shop is the agency shop, under which employees must pay the equivalent of union dues, but need not formally join such union.

Section 14(b) of the Taft–Hartley Act goes further and authorizes individual states (but not local governments, such as cities or counties) to outlaw the union shop and agency shop for employees working in their jurisdictions. Under the open shop rule, an employee cannot be compelled to join or pay the equivalent of dues to a union, nor can the employee be fired if he joins the union.[6] In other words, the employee has the right to work for a willing employer, regardless of whether or not he is a member or financial contributor to such a union.
