I'm with Jerome...I've been screwed over by American management, and also had problems with Canadian, Australian, and UK managers in some places. Weaseltry knows no borders. Some schools, especially certain chain English mills, will tout their Western ownership or management as making them more trustworthy. In reality, these places are quite often worse to work for than the purely Chinese affairs.

I also agree in that TEFL in China is one of the relatively few industries where experience can actually make it harder to find a job. Too many schools will pass over people who might teach a better class but know enough to know when they're getting abused, in favor of newbies who will quietly take whatever they're dished out.

Meanwhile, yeah, Perlandas is pretty bad news. Second only to Frank Zhang in the China EFL Dishonor Roll.
And it can't be said enough: never never never NEVER pay anyone, regardless of passport, to find you a teaching job in China. One of the worst possible mistakes one could ever make in coming here.
