Oh...and I forgot to mention that I was a union rep too for several years before I realised they were more corrupt (in my opion) than the management. I had joined and been elected as I thought we I could bring sensible discussion to the table: I soon realised that this was not what was required and it was all about point scoring, saving face, acting tough and showing how good the union was by 'biffing the management on the nose' - regardless of the topic being discussed and how good/bad an idea it was. The rule was 'listen, mistrust, say no, counter with something else, tell employees how good you are/how bad management are.
Not my idea of morals and/or negotiation. Before anyone asks it was the TGWU.
