This has been on the cards for a while and to be honest the Pakistani/Bangladeshi community need to change and start integrating.
You never see any female staff in any takeaway/restaurant. That needs to change, it's uk not Pakistan and its not in any way racist to point that out. Most places are family run joints and it would be a lot better if all the family were to help out.
I can see why they want to use imported staff as they are dirt cheap, have no rights etc but then they start on the benefits gravy train and it takes the piss hence the gov are stopping it.
It wouldn't hurt for them to integrate more as well, the only time 99% of their customers see them is at work, they normally all live together. Just visit spark hill Birmingham some time. Not healthy.
I'm very good friends with several Bangladeshi and have attended their family functions but the way they have been indoctrinated by religion is bad and will take a few generations to sort out, the kids already are kicking back and I don't blame them. The girls are pretty much breeding machines and don't have an expectation of a career.
So to the point of the OP, its a very good thing that workers from Asia are being stopped, they can do what all other normal businesses do - train and recruit the best person for the job, not restrict it to male Muslims.
