The reason wages are going up for HGV drivers is because for years they have been surpressed by multiple companies using cheap foreign labour to keep wages artificial low, now that cheaper foreign labour has been removed the wages are finding their way to what should be the real levels.
The problem was the middle classes with their white collar jobs that were never competing with cheap foreign labour were never bothered about blue collar workers having to accept poor wages, zero hours contracts forced self employment and all the crap that being in the EU brought with it.
When the vote came in to leave the EU the people that for years that were being undermined taking for granted and ignored suddenly had a voice and a chance to have their say. These same people couldn't give a rats arse about not being able to buy a 2nd home in the Dordogne, they wanted a decent wage with dignity and to be treated fairly with proper T&C.
It all could of been avoided but now we are reaping what we have sowed.
It won't end here the UK was the 1st wave the Dutch are having similar problems within their society and the EU are scared if they get a vote to leave the working class will give the same outcome the UK did.
The Dutch are just waiting to see how it plays out for the UK before they react, this is one reason why the EU is determined the UK will crash and burn.
