The only weapon you have against the people who want to mess up your life is to leave.
I left when, after promising another flying tour, I was posted to MOD in London from Lossiemouth so I elected to walk - best decision I ever made. Now senior Captain with CHC Scotia and enjoying stability and control over my life (still living in the same house we built in 1990).
CHC is crying out for experienced pilots so now is a very good time to transfer your skills to someone who only wants you for your flying ability - no secondary duties - come in - fly - go home.
