To Shaw & Mr Carter,

Here is how it works. The immigrant seasonal workers do not work directly for a British employer. They are employed by a labour gang boss on contracts signed in their home countries, where that contract is enforceable in law. Gang boss has a contract to supply labour at legal wage limit plus a margin - otherwise the British party would be breaking the law. Gang boss pockets the money pays out the amount agreed with the worker then deducts travel and accommodation at extortionate rates. THAT Mr Carter is what your EU freedom of movement allows.
