Well, it's pretty bad form to reply to a deleted post. Usually when somebody deletes a post they don't want it quoted, either. But since you obviously need to be "the man" I'll let you have your fun on the interwebs.

I deleted it mainly because it was a fairly unrealistic scenario. Under our PBS you can control every aspect of the bidding process, even unstacking (we have an unstack bidsheet that you can preference). The logic of the PBS will prevent unstacking from even happening, assuming you bid to your seniority in preferences. Under the unlikely event that unstacking happens, we have contractual limits on how many people can be affected.

I still don't think you understand that unstacking happens on line building before the lines are even bid upon. I don't care who builds the lines, neither the company or the union will be satisfied with all the trips left over falling on the same days. They would rebuild the lines, shuffle things around, until the distribution was a bit more uniform. Then you can do your magic in open time, LIW, whatever, but you'll still get whatever line the company chooses to build for you if nothing goes through.

If you guys seriously (and I truly dispute this) can bid one line working weekends and holidays, completely drop it and build another line from the pot that has all the desirable days off, then why do you even bid for lines?

I understand that your complaint is that there's a lot of pitfalls and gotchas in PBS. I understand that you have seen PBS at pilot groups that don't have the workrules that we do go awry. But, I will say this. I have averaged 2-3 additional days off under PBS so far (compared to the lines the company used to build), and have the same amount of credit per month. I have literally doubled my vacation time under PBS. How is that bad in any way?

One last question for you. Have you ever worked under a PBS? What system was it? If not, where are these negative views coming from? CAL?
