There are many that would trade $ for time off and lifestyle. Most modern airline schedules are completely unsustainable for long term health. I am seeing colleagues at EK get very ill around me after more than a decade here. ( something we dont look at or consider when we chase a shiny jet or are driven by the $) . The companies that look at offering lifestyle packages might be pleasantly surprised that they have no shortage of experienced pilots to choose from. Airlines , if they were just organised enough could actually incur huge savings by offering basings and the option of job share , reduced package for reduced productivity etc.
Getting older and doing 90 hrs a month is a concern. Surely its possible to " slow down" . But this is pie in the sky stuff as the beancounters dont care about your cancer , they will just replace you with the next cancer patient in waiting. Come on contract agencies , pay attention , read these forums , turn away from the greed ,and you may be pleasantly surprised.
