Unbelievably stingy company who intentionally mistreats it's employees in order to make a profit. Unpaid work if you don't finish your required duties in the allotted 40 minute lesson time. A very dysfunctional evaluation system which could get you fired. No paid holidays, no paid health insurance. You can get sponsored for a visa but then they own you. Some students have issues (as lightly as I could put that one) Impossible to get a raise. Micro managing. VERY UNSTABLE! Basically, low pay for a lot of work.
