I remember a story my father told me when he started working (in Belgium). It was a bit before 9am, and everyone was standing in front of their workbench. My dad, a farmers son, thought it was weird and started working on his task. A colleague came up to him and said "we only start working at 9". Since then he, like all the others, stood there doing nothing until it was 9 o'clock.
Unions have a "us vs them" mentality, where the boss tries to pay you as little and try to get as much work out of you, and you do the least amount of work for the most pay.
I myself like to see a cooperation more as a win-win situation, where you do something for me and I for you. The more we do for each other, the better for both of us.
