There was one form me, but when this moved to a question, I guess it was deleted. I just asked for some more details and latipinnia (your sister maybe?) provided them. Here was my response:
If he knows a lot about auto parts, he can look to work for an actual manufacturer as a mechanic or something similar. My brother in law works as a mechanic for Lexus and makes loads of money. He worked for Toyota prior to that.
He could also try to get onto Goodyear. The pay is great, the benefits are great, and the work gets less labor intensive as the years progress. My step father worked for a subcontractor of Goodyear making decent money while he tried to earn his striped to get on teh team. He was hired to Goodyear about a year ago, and he's already working less and making more. My uncle has been there almost his whole life too. Truly great company to be a part of.
If you're looking for something a little less niche specific, there is always Wal-Mart. I may be a bit overplayed, but the jobs are always there, the pay is fair, and there is a lot of flexibility there. You can move locations easily and still have work, and you get a partial share in Wal-Mart after a period of time.
AH! For that matter, he could combine all of my ideas and work for Wal-Mart's Tire and Lube Express center. Boom! Haha
*For clarification, I was told your dad knew about auto parts.
Wasn't there a comment here?
