How would you label this case?
a. Blatant age discrimination;
b. Nick has a point, the company has paid enough. How many houses, wives and kids must they fund.
c. The guys home is now HK; he is no longer an expat.
I vote (a) as well as a couple of other answers that are not options there.
when does an expat stop being an expat?
From the Oxford dictionary an expatriate (noun) is;
a person who lives outside their native country;
So I guess the answer is when they move back to their native country and not before. Pretty simple really.
