Much as I get upset about 'human' resources at QR I feel its neccessarey to clear this up before it turns into something it isnt.
I can categorically state that no Chinese or other cabin crew has killed her/himself in the company housing or anywhere else. Dont know how this story started but it is BS, the Chinese embassy in Doha have confirmed that.
The other case relates to a Tunisian not Moroccan cabin crew who did indeed self inflect injuries to herself in the Tech building before a duty. Recent trouble in a personal relationship was the reason she gave the company in the followup enquiry. She has since been relocated back to Tunisia on extended compassionate leave.
Theses are the facts.
