Unfortunately that doesn't really work here. Companies always call pretty much all of a person's former jobs when hiring them, and one bad thing means they lose the job. It's a pretty strict culture here. Americans do try do just up and quit like they do in the States, but, well... most Americans are limited to deadend jobs in this country for a reason. It's both interesting and frustrating, all the more so because you can't really fight the system. The bullying thing is the worst part. Because of all this, absurd stories like the one above aside, I think these job-quitting companies are a wonderful service for Japan.
