Yes if you marry it to a socialist org or the right demo because you can use them as a vehicle to fight for your other things.

The Starbucks union is full of younger folks that made frequent contact with socialists and they put out a better pro-Palestine statement than most socialist orgs lol. Their parent union has shit takes but the SB kids are killing it.

Gotta take a critical view but still try to find an angle for power and expansion. Any opportunity to recruit and to structure test and to accomplish tasks.

This will almost certainly lead you into a difficult but interesting category of worker organizing, which is in industries of the precariat, small businesses that no big union will help unionize, gig workers, and undocumented immigrants.
