I hear this a lot and while it's true with respect to changes in manufacturing, no iron foundries or shipyards, few brick works etc, apprenticeships still happen.
Coming out of lockdown I started with a joinery firm, fair sized job in Edinburgh. They had 14 young lads in their 1st/2nd year and 32 tradesmen. Sparks were a Glasgow outfit so just sent a couple of squads through, no more than 8 tradesmen but 2 young apprentices and 2 fellas on the adult apprentice scheme. Their trainee engineer was a young lass 👍 Painters had 4 apprentices, lead workers only carried 2. The plumber onsite took a slightly different route, they would start labourers then take the keen laddies on as adult apprentices. Stone masons had a couple of apprentices too.
Still plenty of jobs for commis chefs, junior hair dressers. Some jobs are mostly redundant, place along the road from me hires porta-cabin offices/canteens. They don't employ any welders, no need when they can stick a boy a short course.
