I just find it absolutely hilarious that someone who applied/hired pre-merger, with the rates that were in place at the time, could be infuriated at anything in the MOU or contract offer. You're making tens of thousands of dollars more a year than had the merger not taken place, with a company that has a very viable future moving forward assuming management doesn't screw it up.
I don't get the focus on pay rates and being "+X%". The APA has always had this hard on for pay rates while effectively ignoring QOL issues, it goes back decades in their contract. They were always substandard to UAL and DAL.
