Polish staff leaving UK automotive industry like Rolls Royce

Hi, I am a journalist and I am interested whether stories are true, that polish workers are leaving back to the UK so that some automotive manufacturing companies feel the pinch. Is there any anecdotal evidence, especially in Crewe and Goodwood, Chichester ?

Thank you

Probably anecdotal - I don't believe workers would leave back only because some companies should feel the pinch. Unless they were union workers.
