Final answer:
The United Independent Workers of America cannot strike while the collective bargaining agreement's no-strike clause is in effect, and new leadership does not invalidate this provision.
Step-by-step explanation:
The United Independent Workers of America's (UIWA) claim that a no-strike provision is not binding due to new union leadership is incorrect. The legality and enforceability of no-strike clauses in collective bargaining agreements (CBA) are typically upheld unless specific exceptions are met, which are not simply the change in union leadership. Since the CBA is stated to still be in force and contains a no-strike clause, UIWA's right to strike would generally be limited by this provision until the agreement expires, barring other legal issues not stated in the scenario. It is important to note that the National Labor Relations Act (NLRA) does allow for strikes, but with certain regulations and under certain conditions. The Wagner Act and the later National Labor Relations Act (NLRB) provide federal support for unions and collective bargaining, including the right to strike unless prohibited by a valid no-strike clause in a collective bargaining agreement. Overall, the correct statement about the legality of UIWA's strike is likely that UIWA cannot strike due to the no-strike provision that is still in effect and part of the current, binding CBA.
