Let’s be honest, being a substitute teacher (heretofore known as “the sub”) can be a thankless job.  I was a January graduate and teaching jobs were difficult to come by.  As a result, I started subbing.  One of my first gigs was at a local suburban high school.  One of the reasons that job came to fruition was because my mother-in-law was one of the school secretaries.  Remember, it truly is about who you know.
