Nobody chose to be on furlough, you sure on that. When I went away in the UK this year half the places couldn't fully open as they couldn't get staff, the reason everywhere was giving was that people were furloughed so didn't want to work. I know people that were furloughed and have had the time of their lives the past year. Granted there were a lot who would have been massively stressed will bills and family commitments, but to a lot it has been one long holiday. Why else would so many people be wishing further lockdowns.
Seems a strange comment. if a café/restaurant furloughed staff then they recall that staff when the work starts up again, the staff cant just say no I dont want to come back, keep me on furlough!.
if they cant hire staff to fill there spots then thats probably more down to Brexit then Furlough.
there may still be places in inner cities that are struggling to open due to lack of customers due to remote / furlough. is that what your meaning?
