I'm not going to comment on other industry, but I'll give my 2 cents worth on my game. Both sides of the coin.
Commercial fitout. Just started my 19th year in the building industry, all in commercial fitout. Qualified carpenter/joiner, worked my way up to site manager, project planning and now project managment. Our company has been around for over 40 years and used to try and put 2 apprentices on every year since the 70's, I started at the end of 94 when apprenticeships were thin on the ground. I was one of 80 applicants, into 30 interviewed and 10 for a 2nd interview, for 2 positions. You earnt it, it wasn't handed to you.
Come 2002 and we were ringing Tafe schools looking for pre-apprentices as our ads would yield 2 maybe 3 replies from unsuitable applicants. Work was flush, so it's a buyers market, the kids you wouldn't even offer an interview too 8 years earlier were almost being offered the job over the phone! Union EBA rates, 36 hour rdo week and we are doing the begging to the applicant!
So now if your lucky you end up with one good one and a dud. Up until 2003 the company had never sacked an apprentice before, the not so good ones were at least given the chance to finish their time and get their ticket before being shown the door. Only last year we sacked our last two apprentices and they will probably be the last apprentices through the company. Between the 2 of them they had about 120-150 sick days in ONE year! One of the kids was starting to come good and show promise (too little too late), the other was only capable of catching flies with his mouth.
The good kids are still their like the 'olden days', but there is alot more work around and the kids that would normally be knocked back for an apprenticeship are being hired.
The closure of technical schools over the years could be part to blame, teachers/schools no longer pushing 'trades' as a goal, but more of a fall back, maybe a lack of pride in being a 'tradie'? It seems only in recent years has the govenment realised our trades shortage and implemented some better school programmes.
On the job training? Are the previous generation training the current generation properly? I've met some tradesmen in my time who have been in the industry for 30+ years and are completely hopeless! Rough, poor work ethic and can't/won't teach you anything, I called them 'life support systems for nail bags'. You can be old and completely useless, it's not a young only thing!
We had a cabinet maker in our factory, 30+ years with the company, a brillant tradesman/craftsman who kept to himself. Unfortunately kept to himself too much because in that 30 years he NEVER showed any apprentice anything, would only work by himself. Great role model?
Add to the stupidly short timeframes we are given to complete large fitout jobs (and on tight margins), our tradies have no time to spend half a day with the 2nd year showing him how to hang a door, or explain setouts and understanding construction drawings. So the poor kids end up being given the jobs that require the least training / supervision.
Yes, the current generation needs to pull their socks up and roll their sleaves up too, but the people who say "back in my day" I bet their boss thought they, along with their entire generation were usless too. While age brings experience, it also brings a fading memory
