Actually the Oma chap 20 under leave states clearly ....UAE labour law. ...in reference to leave. If you are assigned those crappy 4 day leave blocks email asking, if it is complaint with UAE labour law, which clearly states the employer can only split your leave into two. The employee can request to split it into more than two. For Cabin crew whose leave is less than 30 days, you must email your manager to complain and ask if it is complaint with the law. They are mointering how many complaints are being made over this leave assignment period.
If you don't ask, nothing will happen . We will continue to be sheep. If you do ask, there may be a chance, albeit slim, that something can change. Please encourage your cabin crew to email their managers. If the response is we are not under UAE labour law email back asking for the reference.
