PHILADELPHIA (AP) — President Joe Biden says he doesn’t think an auto workers union strike is going to happen and tells a crowd gathered in Philadelphia for a Labor Day parade he’s celebrating union jobs. The Democratic president was at the Tri-State Labor Day Parade on Monday. This Labor Day comes against the backdrop of increasingly emboldened U.S. unions and a potential strike by 146,000 United Auto Workers union members. Biden tells reporters he doesn’t think the UAW members will strike. Biden likes to say he’s the most pro-union president ever. The president has used executive actions to promote worker organizing and has authorized federal funding to aid union members’ pensions.
