There don't seem to be any.

There was a woman there—I don't know what her relationship with the boss was. I only know that on my first day at work, I saw her crying loudly and repeatedly saying, “Please, don’t treat me like this, okay?” It was terrifying. The other employees all pretended nothing was happening, as if they were used to it. That was way too abnormal, wasn’t it?! Then, every so often, I would hear the woman throwing things and losing her temper. After being there for half a day, I sensed something was wrong and quickly left.
