Work / I'm moving in to Poland in a week.. and I am panicking! English Teacher [11]

So this week my boyfriend were told that we were to move in to Warsaw a week from Sunday for 4 months! He's going to work in a bank, however I am not.

I am an English/ German teacher (I have my faculty degree and masters in English just in case) and I have worked mostly as a private tutor, but for the past 6 months I taught English to kids from 6-9 yrs old. I was confident that I could managed to find something, however when I was trying to find jobs online, I really didn't see much English Teacher's job applications (and most were asking for natives, although I DO have a native degree of English, I wasn't born there).

My question is, while I don't speak a word of Polish, can I get a job in Warsaw for 4 months? (also do I need a work permit?) Or will I spend them mostly at home?

Kudos for any answers :)
