You know your work is stressful when...

On your vacations you dream about it. Case in point: Sunday night I dreamed I was repeatedly hitting a kid. They were nice solid hits on his back. I tried to hit him harder but it had no effect on him. Monday night I dreamt I was filling in for a class on my break and I really didn't want to.

You look at lounge and chaise chairs with a longing to put one in your office. You could catch some zzz's on that lunch break.

You've just taken off work and feel like your time off is running out.

You tend to put in extra hours to get ahead, but you never get ahead with extra hours; instead you get further behind because your list gets longer and longer.

It takes you a week to realize you need to relax.
