That's true to an extent, but President Biden also maintained a de facto open borders policy which undercut wages and drove up housing prices for US union members. This was deeply unpopular with the union members that I know. I'm not trying to start a debate on the merits of various immigration policy options, just pointing out that union members perceived this as a lack of support.
