This is interesting . . . .
How would it be if we all listed the type of work we do, and if it wouldn't be giving up too much privacy, the name of the company you work for.
I'll start by saying that I am retired, so my "official" working days are over, but when I did work, the substantive chunk of my career was at The University Of Tennessee, approximately 30 years carrying a tool kit as an office machine mechanic, which segued into 'puters, etc, and the last 6 years before retirement as a Buyer in the Purchasing Department, buying mostly electronic and mechanical type stuff, but occasionally doing the odd purchase of some other category when the buyer for that genre was out for whatever reason.
