To be honest this is not just a
Halfords problem. In my mind it is symptomatic of Britain (and perhaps other countries) over the last 30 years where proper apprenticeships were shelved in a drive to put more money on the bottom line.
If you couple that with the way all young kids were directed into computer based jobs you were left with a dearth of people with hands on mechanical / engineering skills.
When I started out in the motor trade (40 odd years ago) the apprentices would go through rigourous on the job / college / manufacturer training to achieve the required skill set.
As time passed the training got less and less and in the last 20 years or so I was constantly astounded by the people who were taking a spanner to a customer's 30/40k car.
Such was the skill shortage, valeters, tyre fitters etc were given jobs as mechanics (or technicians which became the terminology)
Unfortunately we now have Blair's dream whereby most young kids are going to "university" to study (for a good many of them) courses that will not net them a decent job at the end.
I do worry for future skills in this country but I suppose the next generation won't be my problem!!
