The holidays are in two weeks, I have already paid for a return flight home as I had every intention of completing my side of the contract. So far as I can tell the plan they have is to keep a number of us until the summer holidays, then fire us so that they don't have to pay us the wages due to us during the summer break. By extending the probation they basically stripped us of our right to a flight home at the end of the year or summer pay if they fired us. However, now that I know they have actually violated Qatari labour law I'm going to make damn sure I get everything I should have gotten and I'm going to go home and find a decent job while it is still the recruiting season for the education sector. Thank you all so much for your informative replies.
