In the spirit of Labor Day, Silvio La Frossia shares his worst job from when he was 23:

I worked for three months as a shipping supervisor in a leather hide processing plant.

It was a union shop and as a supervisor — a young supervisor — I was faced for the first time overseeing union and nonunion labor.

It was a very unfriendly atmosphere with all the supervisors of various departments constantly sniping at each other, and as the youngest and newest, they all came to me.

I was inexperienced in handling and overseeing experienced workers who were much older.

My strengths were in organization, timelines and structure, but not in people management and especially not in a combative and tumultuous labor divide.

I could probably handle it a lot better today with years of project management and, well, years under my belt.
