Where I work we've had teachers from the US, Canada, Australia, New Zealand, Ireland, Uganda, Jamaica, Scotland (that I can remember) and I have to say that there were good ones and bad ones, but that had nothing to do with where they were from.

Schools that hire teachers from overseas run a big risk and some big expenses (as do teachers looking for jobs from overseas) and if someone hires a bad teacherI think it is natural to try and put the blame elsewhere.

It's not fair, but I think we just have to put up with it, if Anna's teacher was a lazy bum, is the person responsible able to say "I hired a lazy bum." I don't know the Chinese system, but from what I understand this person would then be putting their own job at risk, so instead they say "No more Africans."

It's not fair, but then it is self-preservation.

Good African teachers will open the doors for more of their countrymen, I'm sure of that.

Good luck to you all

Mike.
