I mean, from an UAWs perspective, Biden has gone above and beyond most US president's. Bidens a piece of shit but he stood on the picket with UAW..For USian labor that is massive.

News from within the empire - From a leftist perspective
It's also entirely symbolism, though. And now they've endorsed him and helped fearmonger against the orange man, he can (and presumably will) shit all over their workers' interests, same as any POTUS nowadays.
If you ask me (as a non-white- Asian-Canadian) it strikes me as symbolic of the real issues of much of western labor. They're still just bloody opportunists, and they'll take their lumps like anyone else. Doesn't escape my notice, nor the notice of anyone with an eye for history, that western unions historically were the ones who worked hardest to exclude blacks and other minorities from meaningful employment- that they were the ones who championed all the various Asian exclusion acts, and the expulsion of up to 2,000,000 Mexican-Americans without due cause during the great depression. Same as how the "white working class" and peasant-farmers were the ones most actively committing genocides against indigenous peoples.
They're opportunists happy to look away at genocide (and even their own livelihoods- not like Biden is doing them any particular favors here other than showing up once to picket) for the warm fuzzy feelings the empire has their back once again. And I won't have any pity when they take their lumps like the rest of us. Settlers by Sakai might have its issues, but I fully expect the white masses of the west to need a lot more lumps, before the majority of them are able to get back down to earth with the rest of humanity.
They've endorsed Dem presidential candidates for a while, I honestly wouldn't expect much different now. Fain's "glowing endorsement" is disappointing though, I had high hopes for him
