I also worked at this place and have met a lot of other teachers who also have and none of them have anything good to say about this place. I also knew the ex-teacher you are talking about and he was a perfectly normal guy. There was nothing mentally unstable about him in the least, in fact he was one of the most level headed people there and this sounds like a typical Southern Cross smear campaign. They did the same with a Scottish teacher, saying that he was aggressive and unbalanced. I also know the lead teacher he is talking about, this guy was a nut ball! I remember he was a chronic drinker with self inflected scares covering both of his arms. There was also another guy, he was an English guy with a mop of curly hair. He looked like a mad professor and often sat talking to himself and twitching. I didn't really like working at Southern Cross and was glad to be on my way. I would suggest that anyone wanting to work there should stay for the shortest time possible and then leave.
