I started out working in a production machine shop. My father had taught me how to run a lathe and drill press as a kid. So when I got in high school it was easy to get a part-time job in the neighbors machine shop. I used the money I made at the machine shop to pay for a college education to be a shop teacher.
Once I graduated from college is when my work history gets unusual. I taught middle school shop for 18 years and then switched over to teaching introductory computer courses to middle school students for 10 more years. Of course, teachers don't teach in the summer so I always had a summer job and some of those carried over to part-time work during the school year.
My part-time jobs ranged all over the place.
Auto Mechanic
Motorcycle Mechanic
Gunsmith
Security Guard/PI
And at least one summer in every skill area in the construction trades.
After retiring from teaching I got an IT job with a hardware wholesaler. It was the beginning of the office PC era so I ended up being the "PC" guy. "We think our salesmen need computers. You need to figure out which ones to get and get them ordered. And when they come in you can teach the salesmen how to use them." "The salemen would like to have the catalog (40K items) on their computers and to be able to use them to place orders. Write something up so they can do that." The job was interesting, lucrative, and stressful all at the same time. Unfortunately the company got bought out after 5 years.
So I got a job working in an old fashioned hardware store owned by a friend. I ran(ordered, stocked, etc.) the fastener department(two full aisles) and a little bit of every thing else you do in a retail store. I liked the job but decided to quit when I reached S.S. retirement age.
