CHC European transfers
To quote senior management, ".... CHC Europe is one company with regard to employment and HR, all decisions are made in Aberdeen about transfer of personnel between bases..."
There is one gentleman who recently performed the Scotia-Global-Europe switch very neatly ensuring a promotion along the way which was very well handled. Sadly it would appear to be the exception rather than the norm and as others have pointed out, they'll want their pound of flesh first!
Good luck in your ATPL, and regards to all in Thailand!
