I did a research paper last semester on something called 'workaholism' which has been notorious in the US and Japan. Many people become obsessed with work and making money so they don't take as many days off. It's pretty interesting to read about, but it does end tragically sometimes.

I've only had part-time jobs or seasonal jobs thus far so I never got told how many days I can request off. My places of work have generally been very generous with that, except for Six Flags...but I don't work there anymore.
