Does the most senior guy get to pick through the catering and pick out the best the best flavored yogurt too? What about the room on the highest floor of the hotel? Like it or not, there are limits to what seniority gets you and for the most part it's spelled out in the contract. Your seniority allows you to bid before the guy/gal right behind you. It does not guarantee you will fly a better schedule.
What we are talking about (recycled OTP) is not spelled out so perhaps it needs to be addressed by US as a union, not as lone wolves attacking fellow crewmembers. Didn't someone get fired for that last year? The company does not care as long as the trips are getting flown, so it will be us that fixes any glitches.
That said, if a guy wants to stay attached to his IPhone/PDA/Laptop/etc. hours at a time, eating coffee beans to work his/her schedule then more power to him/her. With the exception of OTP recycling, which someone most likely got a bad deal to even get OTP, we should not be *****ing about something a fellow union member is doing, that you could be doing also, but are too lazy or not willing to work for.
