In the last few years I saw nation wide advertising for wrenches and newbies being paid bonuses for moving up and going to work here. Most all moved out to the end user companies because they paid a buck or two more and hour. The other issue is how the dealers are treating their top people. Job burn out and the damage to bodies over many years of climbing on iron is making the older guys check out early. I've seen some of my brethren treated like throw away garbage when they started making those health insurance claims on carpal tunnel, worn out knees and bad back pain. Other issue is the retirement systems for the new guys coming in. The Automotive Machinists Union here has been voted out of the last dealer shop because their retirement plan is nearly insolvent. Someone with more than ten years of service will only get about a quarter of what they should have been paid before the last recession.
We live in interesting times.
I would like to explore this a little more. I see the same issues, too.
One thing to consider are "alternatives" in economic-speak. Lack of mechanics and/or mechanics demanding better pay and benefits makes service rates higher. When service gets super expensive, keeping old stuff running becomes less cost effective to the point where if the customer is a real money making enterprise, they sell it off and buy something newer. Places that are not making money will fold up.
Being self employed and having been previously employed at a low-benefits place, it has always been about IRAs for me. The short time in history where the employer/union took care of your wages, health, and retirement is over. (Thankfully I would say.) Nobody will watch out for your own welfare as well as you, yourself will. I would much rather have cash in hand than a benefits package administered by somebody else.
It is all about incentives.
Much more to say but trying to stick to one idea per post here.
