Maybe its a cultural thing, Asians tend to keep to themselves and not complain about situations. I have seen this in my work place, after so many issues with HR management started to get rid of locals and is now recruiting only Asians....its not a written rule but when you see 95 percent of staff suddenly being Asian then you realise a hidden agenda....so she thinks she can get away with restring herself to Asian only and put minimum effort in service. Not sure if it would work long term.
