Your reply underlines your lack of understanding. Its a pity that your rep doesnt have a better understanding of what Unite-Amicus Section has done for you and can do for you. You ask whats in it for you. That's the nub of your misunderstanding. Its about "we" and "us" not "I." How many times have you talked about yourself in your reply?
Many of the benefits you enjoy, as I do, in our well paid white collar jobs exist because people had the guts to stand up for themselves. I'm not having a pop at you, you have a narrow view because you think its all about striking and preventing progression (a basic tenet of a good union rep is to level things up, not down). As I said, ask Alf about the learning agenda and equalities agendas where collective action has been the only way to create laws and educate employers that isloating people because of their race, gender, disabilities etc is wrong. No-one on here would defend racial harrassment in the workplace would they? Guess who started campaigns on these issues? If we all said sod everyone else, none of this would have been done and we live in a better fairer society as a result. Is that about strikng or going off on Union jollies?
All these things and much more make up what trade unionism is about. If you have crap reps, vote them out and do it yourself. I think you could do a good job and trust me you would get a huge amount of sartisfaction helping your colleagues who for whatever reason cant help themselves.
