I'll I can say to you now Furb, is bring plenty of high quality vaseline for the certain shafting you'll enjoy after you arrive.
Regarding the English language, don't worry, over the last 2 years, management has shown a decided lack of effective communication anyway, so it won't be an issue for you.
Your "contract" is not worth the paper it's printed on and will be altered at the whim of management. They don't seem to understand the most basic western tenet that a contract is not a one sided document, but an agreement that requires both parties accord for any changes.
This was a GREAT company up to about the early 2000's - but from the arrival of CKN, it's been a slippery ride downhill at an ever increasing velocity, now at the very nadir of it's existence.
Look at the lack of any worthwhile awards EK has received recently. We used to be the absolute best and took great pride in our job. It is also a valid question to ask whether this company is now one of the so called "3rd world" carriers. This is the company you will be joining Furb.
As Airbus757 has said, please don't start bitching and moaning on an all night epic when you realise the mistake you have made.
Keep discovering and enjoy your "career" at Emirates.
