Stefan,
If you are a contractor YOU will always go where the money/conditions are percieved to be better, at short notice. Likewise when the market turns the company will get rid of you as soon as possible.
As No Sponsor has pointed out, NH is no longer with J2, in fact he was not in LFFH for over a year due to personal reasons, which is why e-mails/calls were not answered. Why didn't you contact the fleet capt/ flt ops manager instead ?
NH was a good guy... lay off
