we already have a massive shortage of doctors and nurses - being taught on line is not ideal, for sure ;)
If you look at the Road Haulage Association's web site you will find that there is in excess of 75,000 shortages of HGV drivers. That's those that can drive the articulated trucks.
What concerns me about importing labour, whether skilled or semi-skilled, is the impact it has on the home country that they are leaving. Where will that country train replacements, how long will those that live there have to wait for the sort of things that we take for granted?
The problem with HGV drivers is the initial cost and time it takes to train. Most drivers pay for it themselves.
