At this point, skip asking for a raise and go straight to forming a union. It saves time. It implies they should have been taking care of the workforce in the first place. And your colleagues likely need raises too.

Then over demand, because they’ll try to offer less. If they try any technical or procedual shenanigans, show they’ve been caught and double your demands.

Remind them that unions and strikes are the peaceful alternative to violent retribution, and by trying to block unionization they are admitting they’d rather a class war.

If law enforcement gets involved, tell the state that siding with the owners will only escalate thr conflict, and extend the precarity out to the rest of the economy. Stock values will totally tank, and legislators and gubernators will be held personally responsible by their shareholding plutocratic masters.
