I own the company, so it's not an issue anymore...and my job before that didn't involve office/factory work, most of us had our own assigned vehicles...
BUT, I worked for a short time in the office at a factory when I first graduated college. We called it "shitting on the clock" back then (all puns intended...)
We had one "supervisor" who would come in each morning carrying his newspaper, then CLOCK-IN, and then head straight for the office crappier and stay in there for 45 minutes to an hour before coming out and going to work. (NOT one of the shop toilets...but one of the office toilets that were maintained daily in case customers came by. The shop toilets were disgusting...)
I was assigned by upper management to clock him out whenever I saw it happen. Nearly caused a fist fight in my office one day and I had to write him up an official employee reprimand. He was told to "take his business..." BEFORE clocking-in or do it on his own breaks like the rest of production personnel.
