And that is the very point growstuff. Johnson and the Government knew, full well, that this would be a massive problem- and not only did they do NOTHING to prepare, they ACTUALLY send a huge proportion of the drivers and fork-lift truck drivers (and nurses, and carers, and .... and ....) KNOWING full well that this would make matters so so mcuh worse.
Even if you believe in Free Market, in a high/er wage economy (and most of us would agree)- you can't just let it happen without planning, in a pandemic- AND send vast numbers of the good, experienced staff you have, packing with a flea in their ear.
The fact that there is a shortage in EU too makes this so much more difficult- as drivers, having been so badly treated, will take jobs where conditions, red tape, delays, aggro of every kind - and salaries, are better. And now, at this stage, even high salaries will not attract them back on short term.
There is Free Market- and the is total shambles!
