As an EZY lifer skipper having just reached 60 I can tell you that the long days just get harder and harder and for us LCC guinea pigs, burn out is a fact, as the 75% of skippers at my base who are part time will testify.
IMHO it’s not just an EZY thing but a fact of life for airline pilots these days. Skin cancer, enlarged prostate, chronic fatigue etc etc are all things you young pups have got to look forward to, trust me.
The advice I give to the youngsters I fly with - get your command, pay off your debts and go part time - then the job is fantastic.
