Brexit caused us a huge issue with HGV drivers and the Tories did attempt to address this by massively funding training for those out of work to retrain. It didn’t really pan out, it also left us with a deficit of baggage handlers at airports, which again both the civil aviation and govt attempted to address by encouraging our 18-24 year old NEETs to train in, again not very successfully.
Then there’s the roles we know still have huge holes, Nurses/Doctors/GPs/Dentists/Carers/Early Years/Nursery Staff.
Youth unemployment is a big issue and part of it, sadly, is down to lack of motivation and aspiration, which needs to start in Secondary Schools, but many of the careers staff have been laid off due to school budget deficits.
