English is my native language, and I've thought a lot about teaching English, but I'm afraid I would have to be more proficient in Polish for that as well.
The less you know polish the better for you.
You will have advanced classes with people who speak English fluently, but they just want to practice in conversation.
You don't have to sit with them in class, you can go anywhere. just force them to speak English.
I am a computer networking technician by trade
less paid and you have to know Polish terminology.
have lots of cooking experience too
Poland is not US, where everybody goes eat outside.
You will even not find any restaurant where they need to hire somebody.
I am sure I will one day marry my girlfriend and that will make things easier for me as well to live and work in Poland
So start with that. :)
Once you are married you will get temporary permit so you can work everywhere in Poland.
Without that it will be hard to do anything.
As I said. Talk to somebody at school how to get work permit.
Secretary speaks English for sure so you can call them directly.
