No, as someone who is in a union at the moment none of those things change. I have seen all these things happen and more with the union's blessing (and sometimes it was their idea). The only thing that changes is a tap is installed between the corp and the union to funnel money out of our paychecks.
As long as the union bosses get their due they don't care what happens to the rank and file.
