educated English native-speaker
Nowadays it's polarised. There are either (not really in Poland) the well-paying jobs (usually connected to petrochemicals companies or universities in more affluent countries) where you need to be able to create a syllabus with structures and lexis appropriate to the learners' levels, degree of educational attainment, personal situation and learning aims, create the threads and understand how to develop them and follow the syllabus you wrote without depending on textbooks and with the learners prepared adequately for any public examinations they're taking. Or there's a sort of race to the bottom in for example Spain or sadly now Poland.
I've even heard of lessons for less than 60 an hour now in Warsaw and some providers are now employing 'Teachers' without any sort of teaching qualification or even a degree! Ones who are doing English lessons of whatever quality because they're in the country rather than being in the country in order to teach there. That or some sort of hokey 'dual method' where a local presents the core syllabus and the native speaker does God knows what.
Many of the professional Teachers I worked with when I first came to Warsaw are still in the country having settled permanently there however very few are still teaching unless it's private lessons on top of their regular job. Most of those people speak Polish nicely and get the private lessons through personal recommendation. They tend to refuse more students than they take.
There are other jobs for English speakers in PL; in fact more and more. Monolinguals are at a disadvantage though, and unfortunately some of the jobs are at call centres etc.
There's online work, however this is of varying quality and not always stable employment.
