Construction jobs are all "temporary" to begin with. You finish the job and keep your fingers crossed that the company you work for has more work lined up. These were all HIGH paying jobs that don't come along every day like you seem to believe. Quit trying to defend Union Hater Joe.
Those workers are in trade unions and will sign up for other projects unlike us they can jump from one union company to another in the same local. So yeah, eventually they will be working elsewhere making the same money. Look, I agree it sucks for those guys short term but they are in the union and have a trade, they will land on their feet.
Look what the union hater Biden has done so far. He removed two of trumps union busters from the NLRB and he nominated Marty walsh who was a former union president for labor secretary.
Trump's two labor secretaries were a fast food CEO that was a notorious union hater and then Scalia, a management side attorney. Let alone all the RTW union busters he stacked the NLRB with.
Sorry guys, you can pretend all you want and that may work on the less informed but Trump's labor agenda was anti union. In my opinion Making it easier for millions of workers to unionize far outweighs a few thousand temp jobs on a questionable infrastructure project.
