That attitude seems implausible, but once you’ve been in a union, it’s easy to understand.
The union sets up management as the enemy - the only thing that matters is that the union win, and for the union to win, you have to screw the company. Their attitude here is “Okay, so we lost our jobs, but that’s just a minor thing - we put the company out-of-business!”
Setting up a common enemy is one of the best ways of generating unity and power - the democrats are masters at establishing such boogie men (Big Oil, Evil Insurance Companies, etc). That’s card number one in the union deck - you never do anything for the company unless it’s in the contract, and when it comes to negotiations, there’s no bending - management is the bad guy, and the most important thing is that they get screwed.
I see you have worked with unions before.
