I am a new-bee and I want to know what problems or issues you have in teaching in Philippine ?
As my family will move to Philippine in few weeks and I want to teach there. I have an experience of 8 years in teaching.
We don't have any Philipino classes here. Where would I learn Philippine official language?

@george: It's okay not to learn the official languages, as long as you know English. We are practically an English-speaking nation, even if nobody uses that language natively here.

You're best bet would be some international schools as they pay relatively high salaries. There is also the option of teaching English to Koreans; they prefer native English speakers.
