Worst than be in Doha, is to be alone in Doha...
If for you and your family Doha is tolerable, you have made the right choice to stay. All of us have different limits and lifestyle expectations.
Commuting contracts are not for everyone, but it would suit many perfectly. Vietnam Airlines for example seem to have a much happier stable workforce with higher average return of service.
And who said it has to be compulsary? Dont do
anything that you dont want to do. We are free people right?
