Pitts, I hear what you're saying, however there tends not to be room to negotiate with an employer in this little industry, so walking is the only course of action. If enough people walk over enough years from a small operation then any little bit of research (even on PPRUNE) when answering the job advert should help inform as to why the job is vacant and what you'll be getting into.
Oh yeah no doubt although - and for example - I work in finance. I have a duty to report things (a weak word but the detail isn't really relevant) that are not done properly because I become complicit in the poor behaviour otherwise.
One might think it would be possible to report things that are done badly and expect the same formal report back as you would in an accident scenario. That at least removes the most obvious quip that the departing pilot got fired and any complaint is just bad blood/ sour grapes etc.
