Мне нужно описание роботы учителя

Teachers work is so hard. As for me, its the hardest job. Teacher always has to check students homework, has to know all school program, sometimes he has to shout on his students to calm them.
Teacher doesnt have time for his own life. They usually come home at 19-20 oclock and just check homework. They also dont have weekends.
Its hard to be a teacher, but good teacher always grows good people.
