Ever wonder why teachers look so tired? A poll by the All Japan Teachers and Staff Union (Zenkyo) has found that teachers at elementary and secondary schools each logged an average of 95.5 hours of overtime in one month, an increase of 10 hours of overtime from a decade earlier!

In some classrooms, it would appear, teachers might be falling asleep along with their students!

The poll focused on the month of October last year. It included teachers — either with regular or post-retirement jobs — at elementary, junior high and high schools throughout the country.
