In this article some Nobel prize winners talk about their first jobs and the lessons they learned. One of my first jobs was as a scab.
One summer when I was a teenager, the Canadian postal union workers went on strike and I was hired to deliver the mail. The pay was astounding, something like $25 an hour plus benefits when I was earning $4 an hour as a stock boy. The first day was disorganized and we never got out of the depot where we were supposed to be assigned to a postal station. The second day we were taken in a van to a station but the striking workers rocked and shook the van violently and we barely made it in. The company feared for our safety so we spent the entire day twiddling our thumbs. It was boring sitting around for 8 hours but I was thrilled to head home with $200. The third day we were again trucked to a postal station but there was no mail to deliver and by early afternoon it was clear we were going nowhere and doing nothing. I decided to leave. The guy in charge looked at me incredulously but said it was my call. I slipped out a back door but several burly postal workers saw me and started to chase. I hopped over a fence into, of all places, a graveyard. I ran through the graveyard and eluded a beating. The strike ended the next day. For several years afterwards I collected some kind of pension/overtime benefit.
The summer after that I ran away and joined the circus. I worked selling tickets and cleaning up after the elephants. That was also fun.
I learned a lot from both jobs.
