The official line is that there is a lack of truck drivers, which is mostly true because Brexit has prevented a lot of the foreign drivers from working
It's definitely true that they lack truckers. They don't just grow on trees, and when a few tens of thousands leave, well...
This problem has been brewing for decades as the jobs have been outsourced to low cost countries and the drivers mercilessly exploited. Now that some economies have improved and COVID has hit a lot of those drivers are either unavailable or simply unwilling to travel so far and so long in horrible working conditions for so little reward.
Society needs to recalibrate the value of workers who do manual work. There really is no good reason why the average software developer should be paid more than an HGV driver while enjoying much better working conditions.
