No because the company has other options for labor - it can fire it's entire workforce and rehire, or relocate. The same can't be said for cartels which have complete control over their respective markets.
that's like saying OPEC isn't a cartel because you can still get oil from russia or canada.

isn't that union-busting and/or illegal?

It's supposed to be, but it's often the case that corporations are not penalized to a sufficient amount (or at all) to deter this. We've seen many cases where it's cheaper for the corporation to pay these fines and continue doing what they are doing - in that sense the current laws are ineffective.
