If only life was that simple... "I knew a friend" is a ridiculous statement. Why are you even talking here? Listen to people who have actually worked there, not your "friend" who probably just started. They will tell him (her?) many bullshit stories, make unrealistic promises and yes they may be lucky enough to get the visa, but once they do, they will be hit with a shit storm of attitude and abuse. There is the mission creep effect, where they slowly increase the number of hours you work and don't count that as work time, so no overtime. there will be clubs and activities they will add and forget to add to your scheduled time. If you complain you will be seen as a whiner. You will be told to shut up and do what you are told, regardless of the effect this has on your morale or students attitude. You will have colleagues that will connive behind your back and say how bad you are as a teacher or a person. Yes, I am serious, there is a reason this school has such a terrible reputation in the city. So please, before you quote a story about your "friend", spend some time talking to people that have actually gone through the Changshu International School experience. Then more people will start to care about your opinion on this matter. Hope you have a good day.
