I hated the union when I started, though I don't think my objections were as silly as the OP.
It took a few years, but even despite my bias in favor of the company, reality slapped me in the face repeatedly.
My thoughts on the union and many of my coworkers haven't changed.
But management is approximately 47 billion times worse than they are by every measure.
I still think roughly the same of the union as I did when I started. But I'll stand with them any day, all day, every day even for the dumbest things, because somebody has to stand up to management. Even when they do it badly or defend the indefensible...it's quite clear where I should stand.
