It's not really a CPO issue, it's the wicked witch of crew scheduling, JE and the "if I only had a brain" RW, who are the authors of most of the pain that pilots suffer. CPO can not override a day with insufficient coverage, they tried a few years ago and were stomped down. I can give you literally hundreds of examples of denied POs or PEs when staffing was inadequate, including things like funerals for family members who do not qualify for a BR. CPO wants to help, but they do not have the authority to do so. I'm not faulting them.

The main issue is the lack of authority at CPOs, RW and JE are the real problems. AE and especially SL are good people who do what they can. It's nuts how some people treat SL like crap (I've seen pilots hang up the phone on her). She is one of the most well connected people at the whole airline.
