Before he made it big on "Mad Men," actor Jon Hamm went back to his roots, returning to his old St. Louis high school to work as a drama teacher for two years.

Hamm told Wealthsimple that it was one of the jobs he's held that taught him the most.

However, the job came with some drawbacks, too.

"The downside is that teachers in general are pretty under-respected and underpaid," he told Wealthsimple. "That's a real drag."

Having worked in education, Hamm discussed his own feelings about improvements to be made in the field — and society at large.
