QOL is very subjective and different people value different aspects. What Envoy may call bad QOL MESA or PDT might call it good. I can't accurately compare Envoy to other airlines but I can tell you where the complaining is coming from. It's coming for a significant decrease of QOL from the good ole days. We had 300 145 lines in DFW with tons of variety and high value and time off. Now we have 100 lines with less value and less days off and practically no variety. We also have a reserve system that isn't compatible with part 117 and the company and union can't negotiate new rules that work within 117. This causes you to have new reserve rules that is contradictory to the contract.
Also, within the company itself some pilot groups experience better QOL.
Stagnation and lack of career progression and bases closing caused significant QOL issues for some.
