I don't work there. However, I know people that have as pilots and flight attendants for them. I have had an offer to work for them. To answer your questions:
QOL - Non Existant (They are always short of pilots and contunually hiring - What do you think that means if you fly for them)

Pay - Not what it should be

Pilots Happy - Not really (Again, They are always short of pilots and contunually hiring - What do you think that means if you fly for them)

If thats not enough, ASPEN. Look up Aspen + avjet. Regardless of who the reports say, lots of pressure to get the mission completed.

The owner could care less about the employees, hes only concerned with making money.
