I think you've misunderstood my point. I don't find it upsetting/depressing/offensive or whatever to listen to people complain. I feel genuinely bad for people who haven't identified how amazing life is meant to be. Where is the enjoyment in listening to someone whine incessantly for nine hours about "the chemicals the company has put in the mineral water" etc etc (I'm not making that up)? Once you accept that there is little to be gained from spouting endless negativity (and in fact, much to lose) life becomes a hundred times more pleasant.
There's only one action you can take at Emirates that is going to make a difference: grow a pair of balls and resign. Otherwise: I'd suggest not making yourself miserable over it. Out.
