Unless youve worked for Ryanair you won't fully understand the issue the pilots are trying to raise here.
The issue is not whether the airline is safe or not its the fact that many of the people who work there (and not just flight crew) believe that the management culture is unsafe.
Most airlines are a good mix of results and respect focus.
I recall recently during the Libya conflict that Brindisi all of a sudden became a military only airport (i think it was Brindisi). FR moved all their flights to an airport 90 mins away. I believe FR decided to "rebase" all their crews to this new airport and gave them no provision of transport or Hotels. Any respect focused airline would have done the obvious. The Pilots ended up being a taxi service for the cabin crew. This doesn't make their culture unsafe but perhaps highlights the para above
