I disagree. Unions seem to always operate at the level of the lowest member. In the eyes of the union, no member deserves dismissal, or even reprimand. This is why teachers unions support even pedophiles in their ranks.
And the goal is to make all members equal to that level of the lowest member. I used to work with a union and they did not like members that progressed in their job and were promoted to management. They lost that member’s dues and it set a bad example for others wanting to better themselves.
