If you weren't those offshore Indian processing centres wouldn't be necesary as the Indians would be in the UK, competing for your job here.
They are and they do.
There are things called "work permits".
In most of industry these are issued to foreigners when there is seen to be a "shortage" of local workers.
"Shortage" is defined by the employers as "we have to pay these local b*gg*rs too much, so that means there is a shortage, so we must import some foreign workers so as to get pay levels back down to something which enables us to compete with the Chinese".
Government says to business "yes, good point, here are the work permits".
Does this general rule somehow not apply to BA pilots? If it doesn't then, as I said, aren't they lucky, for the time being.
