BYB- not sure if you're brown-nosing for a job, or just a naive kid.
When you have been out in the world for a while, you might understand what these people are griping about. It is not hard work. It is not having a positive attitude. It is not about gritting your teeth and doing the hard yards.
It is about respect.
Sheikh Mohammed may drive a project, but he respects the people delegated with the task. Storming onto an aircraft and screaming at the CSD demanding to know why the aircraft parked next door is u/s tech is not getting excellent performance from your 'team'. It is unreasonable. Firing people for what they do in their spare time etc. is not 'building the future' or weeding out the bad eggs, is it creating a culture of fear. Managers leaving in droves, not because of the enormity of the task, rather because they are not given the authority or the tools needed to achieve their goals.
Let me make it simple for you BYB. Imagine getting that job you dream about, sitting in the RHS of a shiny new QR jet. All those years of struggle, study and application, now you've made it. Go on, close your eyes. Savour the moment. You like Doha, you've met heaps of great people to work with. You are putting in 110%, working your butt off. Then one day, the boss happens to be on board. You are the non-flying pilot, and on short final ATC order you to go-around, which the Capt. performs perfectly, landing the aircraft without further incident. The cockpit door flies open, and there is the boss, screaming at you about delaying the flight. Before you can even respond, he screams "you are both fired, you have 24 hours to leave the country."
Don't mention it on pprune; some wet-behind-the-ears youngster with rose coloured glasses will tell you to move on, get over it, be positive.
Sorry if I seem harsh, but you just don't seem to get what these people have been through.
