Son wants to go into Automotive Tech

I did it for 45+ years, good living not for the faint of heart. Back in the 80s when flat rate was just that you got a raise every time shop labor went up. Now they give you lets say $25 an hour but you never get the raise when the shop rate goes up. Back in the good old days we were at 40 % making $90 to $100 G a year. Busting *** 10 hrs a day of course. If you are good, fast and fed IE sucking the dispatchers you know what you will do well. Now get training, work for someone else and then open your own deal. Your body will also start to break down and by the time you are 50 you will be done. Although I know of a guy just retired from a dealer as a Trans tech at 73. Ya pay your $$ and you take your chances. Reccomend it as a carrier F NO.
