There are probably a thousand different opinions about this situation - but I also can't understand, like several other posters, why some are saying that drivers have gone home because we 'voted to say we didn't want EU people here'. I don't remember that being as issue at all - we thrive on tourism and foreign visitors, and have always depended upon foreign workers for hospitals, transport, fruit picking etc. It was never suggested that workers should go home and never come back.

What newspapers were you reading in 2016? UK media coverage was was mostly saying how the immigrants were a liability, taking jobs, housing, burdening the NHS.etc.
DD works for the NHS and says many European workers left their jobs there because of the atmosphere regarding the vote. You may not have felt it but they, as the foreigners did. They went back to their home countries where they felt more comfortable. Why should they go back to the UK and what has the UK to offer that they don’t have now, there is no free movement of workers?
They were short staffed in hospitals before Covid, now it is worse.
