I think this thread can be summed up by saying we now have a generation of very tired pilot who is both physically and mentally unable to sustain 4-sector days more than 3-4 times per week (a phenomen brought about by the low cost sector). The airline industry, like most, wants maximum output from it's workforce but the specific demands are at odds with the basic nature of the aging human being.
Consider a typical office job where you have been in the same company for 10-15 years. You're likely to be in a senior role overseeing and managing a team of workers. You would be expected to be far less hands on than you were a decade ago. It's not the same for pilots, the expectation is that regardless of seniority and physical age you will need to perform the exact same duties you did when you started off, and according to the same frequency. This was OK in the halcyon days of 2 or 3 sector flying but not now.
The industry has no interest in addressing the issue of long term pilot career sustainability. It does not need to fear that it's senior workforce will be seeking a way out well before retirement age. The supply vs. demand situation is in their favour, hence why the low cost sector focusses almost exclusively on cadet pilot recruitment. The irony is that some of you who have come through this very system are now finding the career unsustainable. A younger, cheaper workforce will take care of everything whilst driving average salaries down. All this time, the senior pilot workforce will sit fat, dumb and happy ignoring the not-so-very-blatant ageism that has been going on now for nearly a decade.
