Two months into the new administration, labor leaders are proclaiming Joseph R. Biden Jr. to be the most union-friendly president of their lifetime — and “maybe ever,” as Steve Rosenthal, a former political director for the A.F.L.-C.I.O., said in an interview.
Mr. Biden has moved quickly to oust government officials whom unions deemed hostile to labor, and to reverse Trump-era rules that weakened worker protections. He has pushed through legislation sending hundreds of billions of dollars to cities and states, aid that public-sector unions consider essential, and tens of billions to shore up union pension plans.
Perhaps most notably, the president appeared in a video alluding to a union vote underway at an Amazon warehouse in Alabama, warning that “there should be no intimidation, no coercion, no threats, no anti-union propaganda” — an unusually outspoken move by a president in a standard union election.
Yet Mr. Rosenthal and other labor advocates confess to a gnawing anxiety: Despite Mr. Biden’s remarkable support for their movement, unions may not be much better off when he leaves office than when he entered it.
That’s because labor law gives employers considerable power to fend off union organizing, which is one reason that union membership has sunk to record lows in recent decades. And Senate Republicans will seek to thwart any legislative attempts — such as the PRO Act, which the House passed this month — to reverse the trend.
“The PRO Act is vital,” Mr. Rosenthal said. “But what happens now in terms of Republicans in Congress, the Senate filibuster, is anyone’s guess.”
