Interestingly, on this, I do university admissions, and in the 20+ years I’ve been doing it, between 2000 and 2020 it was really rare to see a 17 yo put a part time job on their UCAS form. Very few, those who did usually on the poorer side, had a job at that age. Last year and this year all of them had put jobs on their form - usually bar, retail or casual work, but the change was really striking. Didn’t seem to correlate to background, either - the wealthier ones also had jobs.
I’m guessing that for a fair number of teens, part time work was a way they could actually get out of the house during the lockdowns, and they didn’t feel too vulnerable to Covid, so it was attractive as something to do. I also reckon the post-Brexit labour shortage has a role to play - restaurants and pubs are hiring teenagers because of lack of staff, when previously they wouldn’t have done, maybe?
In any case, I think there’s a bit of a shift under way, and lots of young people are actually getting part-time jobs at the moment. There’s plenty that’s annoying about that generation - all the gender stuff and an obsession with mental health issues and so on. However, they party less, they drink much less and don’t tend to take drugs, they work hard at school, and they seem to be keen on getting out there to do part-time paid work, too, all of which is pretty admirable.
