I have no doubt that they have bent the CBA to keep the planes moving. I don't think the trade you mentioned is nearly enough though. This would give the company a tremendous incentive to staff for the lean months and critical pay through the busy ones...harming the career progression and quality of life of of all of us in the process. As counter intuitive as it sounds I would reccomend not trying to negotiate for 200% when you pick up open time. Doing so weakens the unions position if they ever do decide to negotiate for something in exchange for 200%. Why would the company ever give up anything for the opportunity to staff and upgrade less if they are already getting it for free? Show a little unity and respect for your peers and pass on the quick buck for the greater prize In the end.
