Whatever you want to call it our union is using our negotiating time and resources on this when that time and resources should be used on trying to better our own sitation. Why don't they start with "pay equity" for our own members?!?
Last round the members felt like they were pulled through the ringer after the threat of a lockout in summer. When it came time for the fight to start they felt like they had just been through a 12 round fight when in reality nothing actually happened. It was a brilliant strategy by the corporation and they played us like a fiddle. And it was exasperated by the fact that we weren't really asking for anything besides "pay equity."
IMO instead of joining forces with another faction we should further segregate and have separate unions for outside and inside workers. Think about it this way: would we gain more joining with Purolator for instance, creating a super-union, or do we gain more in fighting separate battles then pointing to each others victories as part of our own negotiation? The supervisors just got a nice little raise, without even trying we should be able to get what they got, that should be the starting point, and their (separate) union did a lot of the leg work for us.
Bigger is not always better, and with the money flowing through our union I would be shocked if there isn't some foul play going on.
