Here are some changes....
Utilities
In my contract EK is supposed to pay for my utilities, but somehow during the financial crisis of 08, they imposed a cap and I am liable to pay if I go over that cap. Read thread on DEWA
Education
EK imposed a 90% cap for which I am liable for the 10% beyond the cap. This was after I signed my contract
Leave
Productivity threshold
Medical benefits (non prescription medicine now chargeable -previously not)
This is just the tip of the iceberg.
There is no reason why you should be asking this question if your supposed friend is working in EK. I wouldn't recommend my friend to work here, you should re-assess your definition of friendship.
Please read the threads in PPRUNE about EK - you have been warned mate
