There are lots of more up-to-date lists than the one I cited, including a 2009 OECD report which gives $9186 as the entry level salary for teachers.
The latest figures do actually show 5000zl as being possible - I don't remember the terminology (pawian will, where is he?) - but a diploma teacher who also marks/creates exams and does a little bit more can make 5000zl brutto.
As Antek actually says - she'll be getting also extra money for teaching there, and with all the little bonuses for doing other things, 5000zl is quite realistic.
...so, anyone have heard of any upgrading in this domain? i mean salary upgrading?
What makes you think that they even want you?
