Same here khalid, my friend's husband left carrefour along with some other colleagues (muslim and non muslim)

They have been asked to resigne but did not get fired.
It seems that a lot of companies in doha are doing this.
However, I don't think that an employer will ask his employee to resign if he did a bad job or asked for a bribe...he will just fire him without notice.

I think it's just their way to take the costs down.
