The problem is, this is exactly what you would expect from a union that's working.

If the union is successfully scaring the management from pulling any shenanigans on the good workers, then, they have a lot more free time for the borderline cases.

As for moral character: let me introduce you to the average person in management at a large corporation!

Unions may not always do the right thing. And there are lots of cases out there where unions have too much power or abuse that power. And sometimes you have an annoying co-worker who is so zealous about taking cases to the union that they seem to be in an extractive relationship with the company.

But that just means that unions are another human institution. Apparently the nearly-infinite number of cases where management abuses their power doesn't count? Where management is in an extractive relationship with the company?

If you want negotiating power over certain issues, for many kinds of workers or concerns, unions are the only game in town.
