Don't ask an Air Mauritius pilot when last profit sharing was paid - it's simply too long ago.
The housing allowance is inadequate to rent a house of an acceptable standard, so one has to be prepared to pay in from ones own pocket.
Leave was not mentioned by Dessas as part of the package. The allocation is 30 days per annum. Presently there is a moratorium on leave (there are some exceptions), normally very little leave is allocated to pilots over the peak period, from about November to February each year. Leave is presently approved at very short notice, also cancelled at short notice and allocated (forced on you) by the company without consultation. Hence you could be "allocated" leave whilst your children are still at school.
