Being an author & speaker is mostly fun, although it does have moments. However, I can think of far worse jobs I could be doing!
The worst job I ever had the misfortune to work was at UPS. I worked in delivery records, and had to be there at 6am in the morning. I lived over 30 minutes from Little Rock at the time, so I had to get up at 4:30am - and I don't care who you are, that hurts!
At the time, we had to keep up with our time card and there was a code for every duty. We had to account for every minute of our day. We were only given so much 'down' time, and if one had to go to the bathroom, that was 'down' time.
Sometimes when I arrived, the side door was not yet open - which meant I had to go all the way to the back, through the security check point, and by the time I reached the office, through no fault of my own, I was already a couple minutes late.
I also worked in an office full of women, and it was constant gossiping and backstabbing. (Now I know why I prefer working with men!) You had to stay on the good side of the right people, and even then, they probably still talked behind your back. Office politics were just not my thing, either.
Needless to say, it was very stressful and I made at least three trips to the doctor's during that time with stress-related problems. After six months, I was SO happy to land a position in my field of photography and escape!
So, what was the worst job YOU ever worked?
