A lot of customer service jobs in call centres require you to be fluent in several languages. There's many of them in Kraków and Wroclaw and depending on your language combination you can earn up to 1500 euro a month, which is a pretty good salary in Poland. Speakers of German and Scandinavian languages generally earn the most from what I've heard. I've met some people working these kind of jobs and it seems like a decent gig, I don't think I'd mind doing something similar for some time and it's a good way of relocating to Poland.
