"Vacation Time"

A lot of people assume teachers have tons of vacation time. I ran some calculations based on the hours I work. Interestingly enough, I work enough to cover all of my "vacation time." Averaging 40 hours a week, every week. What isn't included in that calculation is what I've been doing with my spring break, grading papers. All good teachers use "vacation time" to work, go to graduate classes, or for professional development Am I complaining? No. I chose education, not business school for a reason.
