The government’s focus, at least officially, is almost entirely economic. Migrants are welcome insofar as they benefit ‘us’. These human beings, some of whom are already sitting as ‘stock’ in our national store cupboard like tins of tuna for a rainy day, are there to boost production at UK plc. The new policy contains some pro forma references to the ills of exploitation, but imposes vulnerabilities on a whole new group of people who are currently able to walk away from a boss who skims their wages, extracts unpaid overtime, touches them up or worse. The message: you are here to do a job, a particular kind of job in a particular industry, and if you lose it then home you go; even if home, for all emotional and practical purposes, is here. Faced with such options, many will do what it takes to stay, and their managers will know that they will.
