I don't know how many times you need to be told. DO NOT ANSWER your phone on a day off!!! No matter how much it benefits you, all you are doing is helping the company that has refused to give you a raise, an increase for the cost of living, an increase in housing, travel in economy while dead heading and so on. In addition to that you are denying another pilot a job.
And anyone that would even consider doing it for less then 3000 dhs a day is even a bigger idiot.
