I have very little time for unions. Yes they have their place, but my experience of the TGWU/Unite(google oxymoron) wasn't good.
Used to work for a firm that through union bullying went bust. I joined said union in order to have my say during a pay
blackmailing sessiondispute. They took my subscriptions gratefully enough, but when it came to the ballot, my and several of my colleagues who saw that the company could illafford either the demanded payrise or the proposed strike voted against both. These votes were struck from record and ignored.
Before things went much further, the shop steward was found somewhere he shouldn't have been, with someone he shouldn't have been, wearing less than they might have been whilst on company time. He got the sack. Myself and the other 'No' voters all got a whole load of crap for voting against the proposals in what was a 'secret' ballot, and I eventually left. Company folded nine months later. That was six years ago, and many are still out of work. Being in the union helped no-one then, and it helps them even less now. Some firm pretend to work with the unions, but whilst they give the unions the time of day, the companies tell them what they are doing rather than ask permission.
Why any one would pay someone a percentage of their hard earned cash to be treated like a mindless mushroom beats me. I naively made that mistake once, never again
