Write a short description of 3 jobs: Teachers have a flexible working schedule and sometimes it can change from week to week. Of course it's inconvenient. But this job is rewarding, because a teacher imparts knowledge to others and can see how his work has an influence on them. Secretaries usually work 9 to 5. They don't get paid a lot. However, this job isn't very difficult. A secretary needs to be polite and responsible. Waiters may have various schedules. They can work shifts, only weekends or evenings etc. Their job is difficult physically and morally, because they are always on their feet and have to serve every client quickly. They need to be friendly, polite and patient with their customers.
