I'll tell you what I was told by my hogwan manager:

"If a restaurant doesn't make any money, we change the staff"

So everything gets blamed on the teachers, even when we were taken to a restaurant for a meal and the directors wife was drunk, saying "F this and F that, making a little D**k with her pinky and describing the S** life of her dog. She was asked to tone down by the restaurant manager, and we got lots of glares and I was very uncomfortable with the whole thing.
She went on to teach 5 year old girls to say tough things in English, like "Get lost" and used to steal the students pencils.

So shortly after this episode, some teachers lost their job when perhaps it should have been the other way round.
