I just don't know whether things will improve, or devolve as the school settles down to business so far.
Personally, i LOVE teaching, and being in the classroom, but i haven't had much chance to yet, as we've been writing lesson plans, and doing promotional work so far. Supposedly we're moving to a more central location (ala People's Square area) from our current one in Zhabei (more industrial/residential) sometime in September.
As for salary, the first month is probationary, and only about 5000rmb, but then it goes up to 6400 after that. But the apartment is free, and is a perfectly acceptable place (in my opinion), which is worth a lot in Shanghai, where rent takes the biggest chunk out of one's paycheck.

So far, i have yet to hear of a school in China that ANYONE can recommend working in, especially in the big cities. It seems like Chinese administration doesn't treat any employees as well as Americans are used to being treated. The Chinese employees seem to take a lot worse than the foreign teachers, even, and Like it!

I still haven't signed a contract (haven't been asked to yet), so i'll see how things go once i'm locked in. The other foreign teacher here seems ok with stuff, but gets grumpy at lastminute schedule changes, which seem the norm here.
Feel free to ask any other questions. I've only been here 2 weeks though, so i'm not sure what will change in the future.
