> There's is not a labour shortage of lorry drivers. There is increased demand, reduced supply (due to a pandemic on both counts) - but plenty of people who can drive a lorry and are licensed
Not sure what you mean by that, BBC mentiones a lack of 100.000 drivers just a few days ago: https://www.bbc.com/news/57810729
That's a shortage, no matter how you turn it regardless if people are not available or simply don't want to do it.
Sure, pay can increase but so will the price of goods and components, having a knock-on effect on the rest of the economy and making UK less competitive as a result. Companies want to move stuff and they see no profitable means to do so.
I'm in The Netherlands, there's a driver shortage here too but it's mostly eastern europeans filling the void. With an unemployment rate of 3% why bother with a boring away-from-home job? Unless Trucking is your hobby essentially. I imagine most people in the UK feel the same way; there's better jobs available now with the economy opening up.
