Pros
There are not sufficient pros to attempt to make a positive image for the HCT. If one could say something positive about the establishment is would be their past. In the past ( I worked there for nearly 15 years) it was a smooth effective system. If you are very new to education and the UAE, it may be OK for 1-2 years to collect cash and gain experience. Don't worry about breaking your contract, they will not hold their end. But - the problem with this - is they hold the key to your release with paperwork. Yes, government clearance letters you need to exit properly and legally ranging from clearing phones, electric bills, and so on. If these are not clear you could technically be held at the airport. If you risk that, just be sure to send any significant others a day or two before you. No need for all of you to be held - which could technically happen.
Cons
Have a look at Daves ESL job forms. Contracts are being broken, housing benefits downgraded in a very expensive rental market (rent will cost $20 000 usd minimum for a place even in the countryside), education allowances slashed, and to be very fair - people are bullied by upper management. Recently in Dubai a female teacher, after getting new contract details, died of a heart attack. No joke here. There are other places. Also, this is not a hospitable environment. Do yourself a favour - stay clear.
