What you’re describing is akin to the pressures that come from nearly any job where one is earning a six figure salary.
You’re flying one of the most sophisticated bits of kit out there with corresponding automation levels doing a job that is done tens of thousands of times a day globally with very few issues. It is not rocket science or pioneering/high-risk surgery.
Tiring/stressful/hardwork etc – yes of course, but that’s what the company is paying you for – probably at a cost of around £10k/month. Why not work part-time?
