The International Longshoremen’s Association has confirmed plans for a port strike on the U.S. East Coast and Gulf of Mexico starting Tuesday. The union, representing dock workers from Maine to Texas, cites long-standing wage issues. The strike could severely impact supply chains, marking the first coast-wide strike since 1977. President Joe Biden stated he would not intervene to prevent a potential dock workers' strike if a new contract isn't reached by the Oct. 1 deadline, emphasizing his support for collective bargaining. The Taft-Hartley Act allows presidents to impose a cooling-off period in labor disputes.
