You have to realize that the raises in the article you linked were only offered BECAUSE of the unions, right?

Starbucks could easily have given the same raise to union workers. Would have been a simple contract amendment that any union rep would instantly sign.

But STARBUCKS chose not to do that, because they want unionizing to look like a bad idea.

This isn't starbucks saying "we want to give EVERYONE raises" and the unions saying "not without our approval you dont!"

This is starbucks intentionally giving raises they otherwise wouldnt have to non union employees, in order to make them want to stay non union.

If the unions give up, starbucks no longer has any reason to try and play nice like this, and can go back to a "you'll take what we give you or we'll replace you" model.

Any problems employees experience from being in a union are problems that starbucks intentionally creates for union employees, because they want to kill the union.

And it saddens me that your response to that, as a presumably intelligent, adult human being, is "well, we should just give in to the corporate overlords, remove any potential checks and balances against their ability to exploit their workers, and just trust that they care more about being good people to their workers than they do about profits"
