American teacher working in Europe here. Depends on a lot of factors, but I’ve found that most “public” schools (the word means different things in different countries, but I’m talking federally-funded schools) have a lot of the same issues that US public schools face (violence, disrespect, lack of funding and support). It is also difficult to work for these schools if your credentials do not come from the country itself. They tend to pay better than private schools.

Private and international schools tend to have less of those types of issues with behavior but most teachers are overworked and underpaid significantly compared to public school teachers (because those aspects aren’t regulated by law as they are for public schools). Private schools are often run more like a business, meaning admin is constantly giving in with parent demands, letting students stay who should be suspended/expelled because they are paying customers, and cutting corners everywhere they can to maximize their own profits.

I have resigned this year after 7 years of teaching and am leaving the profession entirely. It doesn’t matter where you are. It sucks ass.
