Not burnout, just fatigue and tedium.
I would say now that in my late 50s, I may have been getting too much of that tedium and fatigue - to the point you could say I'm close to burnout. Since then, we've been working harder and the FTLs are being increasingly ignored. I used to sit on the company Fatigue Management Committee and used to hear comments such as "Sure you're working hard, but it's within the limits". I liked to point out that limits are not targets. The engines can be used at full power for five minutes on every take-off as that's in the limits too. But if the pilots started doing that, they would end up with plenty of time off while the aircraft are grounded during frequent engine changes.
Most pilot manning projections are based on all pilots working to 65. This isn't happening - most retiring from my airline are stopping well before 65 and I suspect it's the same with other airlines. I will not be flying an airliner past 60. I was were to, I would probably be dead before 65 anyhow.
