PHILADELPHIA (AP) — President Joe Biden has told a crowd gathered in Philadelphia for a Labor Day parade he’s “celebrating jobs, good-paying jobs, jobs you can raise a family on, union jobs.” The Democratic president was at the Tri-State Labor Day Parade on Monday, speaking about the importance of unions. Labor Day comes this year against the backdrop of increasingly emboldened U.S. unions and a potential strike by 146,000 United Auto Workers union members. Biden likes to say he’s the most pro-union president in history. Biden has used executive actions to promote worker organizing and has authorized federal funding to aid union members’ pensions. Monday’s event was hosted by the Philadelphia AFL-CIO.
