Korean work ethic: Are we really working too much?

Since I becamse a full time job worker, I couldn't stop questioning about Korean work ethic and how Korean ppl are handling jobs, working style in general.

And while I was talking to my several international friends, Koreans seem to have very little holidays, less generosity when it comes to individual's life/health conditions, having to work till late time became common sense in some industry... etc

So I wanted to share my experience and thoughts about this topic with you. Hope you've enjoyed! Thanks for listening again :D
