How many hours in average does a secondary teacher spend for his/her job per day?

This includes every work for the job- at school, at home, etc. Do teachers still have time for leisure and other matters at home? I mean, isn't hard to meet the needs of both work and family? Teachers in your own experience please, do you guys have time to relax and enjoy the atmosphere; even on weekdays? Thank you. I would love to hear your opinions about this matter. It would be better if a teacher personally would answer this stuff. Thanks again, folks.
