NEW YORK (AP) — From auto production lines to Hollywood, the power of labor unions is back in the national spotlight. But despite historic strikes and record contract negotiations seen this year, there’s still a lot stacked against organizing today. Rates of union membership have been falling for decades. More than 35% of private sector workers, for example, had a union in 1953 compared with about 6% today. Experts point to changes in the U.S. economy, ample employer opposition and growing political partisanship seen in recent decades. And, under current federal and state labor laws, desires to organize can only go so far without policy change.
