Seems that being a teacher in most countries is hard to get job and very underrated.
In Serbia is also not easy to get a job at public school, but not because of education, but because of cutting off as many people as possible from the budget financing. That means, it you don.t have the norm in one school, you will have to work in 2,3, even 4 (if your subject has just two classes per week, for example), which means that one who is in position like that in reality is spending much more time connected to work than it is officially recognized.
Salaries are the lowest in public sector, baby-sitter for one kid gets more per month.
Wish good luck to your wife with the job.
