Shane English Schools - Teachers needed in Vietnam

To be honest, there were some benefits working for Shane Vietnam. The local Vietnamese staff are friendly and helpful, and the children in the classes are pleasant and fun to teach. However, I had so many problems working for them that you really should just avoid this school altogether.
Firstly, their rate of pay is lower than the average for working in HCMC. The hours are incredibly unreliable and change from week to week, and whatever hours they promise you, you will lose a whole days worth of wages a month due to them trying to cut costs and having a Vietnamese teacher take your lessons once every month. This doesn't sound like much but firstly, as I said, your hours are not steady throughout the year anyway, and secondly, from my experience, no other English Centre uses this policy this way (some share with Vietnamese teachers, but no other school causes the teacher to lose out from it).
The main thing that is terrible about working at Shane is the higher-ups don't give a flying f*** about their employees or really the children. Everything is money to them, and if you can spread out an hours worth of lessons to cover two two hour lessons, then so be it, you get more money from the students that way. They have limited resources and there's no sign of improvement. Also, when a teacher discovered that one of the children might be suffering from abuse, the Dos chose to turn a blind eye, because upsetting the parents would mean upsetting the payer.
Also, they treat their teachers abominably. When I decided to move on to another school, they docked my whole last month and a half's pay-check because apparently I owed them money from being recruited from the UK (I didn't receive a dime when I was recruited, they apparently paid their sister company SaxonCourt for me, and then I was supposed to pay for my liberty - situation sound familiar?) and because they press-ganged me into taking their medical insurance. Upon leaving, my Dos informed me that because they were absorbing my last pay check, I was allowed to keep my medical insurance that was paid up-front for the coming year. Because of this, I decided not to make a fuss, and even carried on working for a further two weeks so not to leave them without a teacher even though I knew I was not getting paid. Since then it turns out, that they have decided to cancel the medical insurance, even though they cannot get any of the money back from it, and despite the fact that I paid for it. This is just a vindictive and horrible thing to do, and the question is, would you want to work for a company who is prepared to screw you over just because the higher-ups are petty, dreadful excuses for human beings?
I would hope your answer was no.
