Most weekends I'd dedicate around 5 or 6 hours to work, so that puts me up to about 61 hours a week. Of course we got those amazing holidays. Holidays when you were still expected to answer emails, mark work, write reports, plan assessments and lessons. One year, I remember working from September through to August, and my total time off was Christmas Eve and Christmas Day. In August the exam results come through, so I was expected to be in school to coach children on their options, and then write a 15 page report on the reasons my department had performed or under-performed.
I appreciate that this has turned into a rant, but don't ever think that your job is harder than a teacher, if you are a software engineer. It's not. I can testify to that. Teaching involves understanding your subject, understanding pedagogy, being a parent, councilor and sometimes prison warden to children who are often going through the most difficult times of their lives. You have to do all of that, while basically performing on stage for 5 hours a day, and your lunch break is spent ramming food down your throat so you can get out to the playground on time to supervise the kids out there.
An ex-colleague of mine has asked me to go back into teaching in his school. My response was "okay" can you pay me 150K, because I wouldn't do it for anything less.
When I was in HS, it was not uncommon to have lecture most days and a graded assignment once a week or even less. This is obviously a lot less work for teachers. In the best cases it can be a 7—4 job with summers completely off.
I certainly don't deny that teachers spend a lot of time working on their "time off". But that said, I've known more than a few teachers personally, and yes, they still do get enormous amounts of time off. Heck, a bunch of them will even admit it is the biggest perk of teaching (because otherwise there aren't many).
Teachers have plenty of real, valid complaints about the environment of teaching, and more importantly, it's clear with the current teacher shortage that something is really broken. Still, I don't think it wins them any supporters when teachers try to deny that most of them have vastly more time off than other professionals.
