I think the thing people don't appreciate about teaching is about how full-on it is.
I used to work in business - if I rolled in late, no-one really cared;if there was a deadline for a particular project, I'd work extra hours; if I was bored during the day, I'd get up, have a cup of coffee and have a chat to someone by the machine; timing for lunch was up to me; if I had a hangover, I crawled into my corner and did the work at a slightly slower pace.
I cannot be late for school - I arrive at approx 7:45, and prepare for the day, talk to colleagues, get out resources, give out books ready for work to save time later, etc.
There are always DAILY deadlines at school. Book MUST be marked by the next lesson - lessons are planned with prior learning and understanding taken into account. Assessments MUST be done. Tomorrow's lessons MUST be planned in advance. This continuous need to mark and assess work often means that I have to take work home in the evenings and at weekends. Planning for the week means that I have to plan at the weekend. (Note the 'have to' there - I have no choice.)
If I am bored during the day, I can't go to a colleague's classroom and have a coffee and a natter. I have to keep going.... whatever I feel like.
Timing for my breaks are set in stone. I cannot move them. I have 4 morning breaks (one is spent on the playground) and no 'free' lunchtime (I do 3 lunchtime clubs and I have two lunchtimes that run half and hour short due to other commitments).
I cannot drink copious amount so f alcohol during the week. a) It's not nice if parents smell your breath, and b) a raging hangover with 30 children is like an idea of hell.
Your OP, I'm afraid just shows a lack of thought about what a teaching job actually entails.
