Another possible part of such collective agreements is that the employer will withhold union dues and hand them to the union no matter if the employee wants to join or not; to prevent the 'free rider' effect where some employees get the benefits of collective bargaining without paying for the representation (the appropriateness of this argument can be debated, but that's at least the stated intent).
In about half of USA ("right to work" states) such agreements are illegal, and in about half of USA unions can have such practices.
The effect is every grocery chain in the area has the same price-fixed wage they offer, price-fixed benefits, and etcra.
Don't like your wage at Fred Meyers? too bad, the safeway down the road is in the same union contract and thus the same wage.
Get kicked out because an unexpected financial/medical expense killed your ability to pay dues? too bad, none of the other chains in the area can hire you until you pay off the back dues, that you can't pay because you can't get a job.
Union is holding a vote to strike and pushing out misleading information when really the only provision the employer is objecting too is a new one that requires the employer pay the union dues for any unfilled position because the union just wants to make more money so they can vote themselves into a raise? too bad, you can only communicate with people on your shift at your location in your section of the store, the union however has mandated access to break rooms, as well a mailing and email broadcasts.
What people don't seem to get, is that sometimes, the power unions get from getting so large, can be used against the employees, not just the employer.
But you can't even bring that up without getting strawmanned as a republican union hater.
I haven't even gotten into programmer unions, with high dues and 9k initiation fees that get voted for because nobody who votes it will have to pay it as they are already in.
