Quite often I have heard in practice that teachers are tired and that they have been looking for work outside school several times. We still had a teacher at the high school, who was already so exhausted and tired that she had a stroke on the way home from school. (And she wasn't over 35 years old.) Fortunately, she's fine, and from what I've heard, she's teaching part-time again, which is very admirable.
