Is it possible/difficult to find a job in Poland for Ukrainian citizen? (B.A. in English) [13]
As an Ukrainian you don't need work permit to teach your mother language in public schools. But there is low demand in public schools for Russian and nearly not existent for Ukrainian.
To teach English (or do any other job) for more than 6 months per year you need work permit. So that's not so bad situation as you could work for few months, prove yourself good worker, so your boss was convinced to apply for work permit for you.
But I think that your chances of getting English teaching job is close to none. The competition of Poles and British people is too big and you have disadvantage against them - it's not your native language and you need work permit.
Teaching is bad work sector now, because of demographic low. Many teachers are fired. For example in Radom (22000 citizens) this month over 100 were fired, because less children starts education.
