A small add to my previous post:
My cousin is a teacher. She is young in her mid 30s and theaches Bulgarian language and literature. She loves teaching and wanted to find a job on whatever salary at least for the beginning. Then she spent months of searching few years ago in Burgas (4th biggest city in Bulgaria) before she finally found something - a job oppening not in Burgas but in a small village nearby the city. The shcool was smal, unprestigious and bigger part of students were gypsies and thus very few of them attended the classes at all or even at 5th or 6th grade could have hardly spell a word correctly in Bulgarian. Anyway, what is even more the director of this school told her that only Bulgarian and literature isn't enough and she has to study something else as well to teach two subjects. They were lacking a teacher in Geography so she has to go to Uni once again and study a second master degree in Geography and Economics to have a chance to keep her job in the school. And of course she isn't getting much I think for all that something like 500-600 leva.
Now she moved to Varna (her husband is in the army) and  started searching for a new job. Nothing is there - no teachers are wanted. Only one place with temporary contract for just half salary.
