Dear Mr Voodoo2,
if you are hired by CHC nederlands, the you should expect to stay at CHC Nederlands, there is no movement generally between them for example and CHC UK even though both are within CHC europe.
the terms and conditions are different and the employer is considered to be different in practice.
if you want to go to thailand for example you would expect to have to resign and then apply to CHC global for a thailand slot.
basically you have to take the risk, maybe there will be more movement in future but there is very little now
regards
CF
