The kind of jobs most teens have might not be directly related to the career they wish to go into....but that doesn’t diminish their value.
When they apply for grad training scheme jobs which are highly sought after, when applying and in the various interview and group exercises, talking about actual experiences where they have been challenged, dealt with a difficulty etc are so important. It won’t be the fact they operated the till in Tesco that matters for them getting on the scheme but the fact they dealt with tricky customers, persevered with new skills, worked within a team etc that count. Those things also mean they gain confidence in a way you just don’t when always only in an environment with students or people similar to yourself.
Getting a job in a shop means applying, being interviewed, doing training, facing some awkward customers, possibly dealing with a tricky manager, having to ring up to request absence, finding ways to re-arrange life and other things to fit in with work. It’s all really valuable.
If all you do is go to school and study and perhaps do a couple of school based activities, life has been very narrow and sheltered. It’s not impressive in a competitive world.
Weaker students might find that working many hours impacts their ability to do well at Alevel. Good students find 6th Form is the time to thrive with study, extra curricular, a social life and a few hours of paid work. The weaker student might need parents to intervene to manage their time, but bright kids working a shift per week thrive and learn to manage their time and study efficiently. Getting A* at A level shouldn’t require studying every hour God sends and if it takes that, really things don’t bode well for the future.
Yes, keep a balance. No jobs wanting 13+ hours in term time, but one evening shift or a weekend day should be fine. Even doing 3 months and then quitting in the run up to exams delivers huge benefits. People think ‘shop work=not relevant to future lawyer” but they forget the skills and experience gained and transferable benefits.
