Let me put it another way then ....
Is it ok to shaft a relief crew member both ways so he/she works back of the clock both ways so you as W pattern commuter get the best rest to get back home, outside of the base your employed at whilst for example a HK based crew member does all the hard yards so you can achieve that , p##s off!
The majority of all W pattern crew are only interested in themselves and not the whole crew.....sure it does work out sometimes , probably quite alot, but....
the next time I am asked to work both ways back O the clock for a W pattern Capt whose commuting I'm going to tell him where to go...or call it in.
