dont forget one thing
Your calculations are just about what I see. Also if you have already have some of your holiday, then you have been penalized, as the major improvment was that you did not lose so much when you went on leave.
This was very clever of management. Wait until April and then implement it. I imagine most people already had some leave. Also the 767 guys had all of Feb off and forced to take some leave time while the a/c was on ground. Good news is next year when there 1.8 percent pay rise comes they can make it back.
One other point is that EY has no protection for currency shifts, like EK does. The Durhams is based directly on the US dollar. So not only is inflation here hurting you greatly, but the dollar is very weak.
The overall philosophy seems to be give them the least possible and hope people don't leave and alway say more is in your future.
EY housing is one of the lowest in Abu Dhabi, making it very difficult to afford anything than company appartment, some are okay
Overall with only 700dhms payrise a year in contract, there is very little future at Etihad. With the dollar sinking and inflation so much it is only a matter of time till it will cost you money to work here, which is a management dream.
