DEC have been in emirates since the start of the company.Any FO who did his homework will have known that, If you did not not do your homework who is to blame?. Not DEC,not company .
Sorry - not entirely true. There was a significant period of time where it was the stated policy to NOT hire DEC's. It is true that the policy changed about 5 years ago so it shouldn't come as a surprise to those who have joined since then.
