The idea of the warning letters for non-productivity is the "brain-child" of one of the fleet's chief pilots...I think we all know who.
The most effective way to get him "moved" to another position would be to send a copy of that letter to the editors of ALL the western papers with a brief description of the treatment of people in this company. I picture paints 1000 words and its not a fabrication, just statement of fact. I'll bet the US media would have a field day with it along with ALPA and the US3 vs ME3 case.
"Middle East Pilot gets the sack for going to mothers funeral" makes a good headline.
It should have been done a long time ago.
