"teachers hours aren't that high and actually a lot lower than many professions."

So you have a neighbor who doesn't work 8 hours. I have a neighbor teacher who works more than 40 a week and summers too. The average is important, and research shows that teachers, on average, work as much as others. See this article on British teachers working up to 60 hours a week

And this one on American teachers working 53 hours a week

Just because you don't see them physically in the classroom the whole time doesn't mean they aren't working.

They work their summers (that's when they do their training ... what is often included as part of the regular work week for other professions). They grade in the evenings. They buy schools supplies out of their own pocket. This is all documented by a few different studies, you can search my post history for the last time this debate came up for other links.

And yet you are basically saying they don't work hard. That may not sound offensive to you ... but put yourself in their shoes. You just got paid a couple hundred dollars to deal with unruly and ungrateful kids for a full day, with no prep period, and come home to grade and others say you don't work very hard.

They may not mean it as offensive, but can't you see how it is?
