This was on Vermont Public Radio this morning. An aircraft maintenance company out in the mid west is complaining about the lack of qualified aircraft mechanics to hire. An lady HR rep from the company said on air "You cannot just hire high school graduates to do this work."
The hell you can't. That's all we did in USAF. We enlisted high school graduates, put 'em thru a few months of tech school, and then put 'em to work on the flight line as apprentices (3 levels in USAF jargon). They worked under the supervision of journeymen and masters. After taking some courses, getting lots of hands on experience, and passing some tests, they got promoted to journeymen (5-levels). Took about three years for the average guy. And with more experience, and training, and testing, the journeymen became masters.
That maintenance company could do the same.
Then they revealed that they only paid people $12 an hour to start. No wonder they have trouble filling vacancies.
