Inemuri

A couple years' back, one of the interns at my company was found sleeping on the job. And not just once or twice, but regularly. Needless to say, he didn't stay long. But, perhaps that wouldn't have been the case if he'd done it in another country...

...like Japan!

That's right, ladies and gentlemen. Inemuri is the art of "sleeping while present" aka sleeping on the job to show how committed you are to it. 

The logic is that the worker's so exhausted from working so hard, practically 24/7, so he/she can't help but fall asleep at work. Some people even fake it, to impress the others. 

However, things aren't that easy, because there are certain rules to follow as well (which isn't too surprising). So before you decide to try it out, know that only those on the higher rungs of the corporate structure or organization can do it, and you must do it while remaining as straight as possible in your seat.

So, who's napping for real or faking it?
