Its because recruiting is done by penpushers in the HR department. They have no idea that the 17th is just an exam on how to use a book, and you could get a monkey to pass it.
They get there info from a book when they recruit. They are not aware of any higher qualifications applicable to Electricians, In fact the only higher qualification they have heard of is "Under Graduate" whatever the ferk one of those might be! And I have never heard of an Under Graduate Electrician.
So in a nutshell, if like me you have qualifications coming out of your ears and other places, if you cant pass an exam about how to use a book, then you can't possibly be a proper Electrician. That god i work for myself, no bellends telling me what i can and can't do, i didn't have an interview, and the pay and benefits are good as well.
Sorry for the rant, but this sort of thing annoys me. I like a lot of you know some cracking sparky's and other trades who don't have a qualification to their name, but can knock me into a cocked hat when it comes to the job, but they dont get a look in at recruitment time.
