I’ve only worked in Korea, not in Japan or China but I’m inclined to say Korea because:
- they have 눈치 culture which means you gotta respect your seniors and boss and cannot say anything back. For example you cannot leave your work until your boss does
- 회식 which is a type of dinner you have with your coworkers, but you cannot refuse. Your boss invites you to go drinking, you have to go because of 눈치 and sometimes your work details can be affected as a result of these dinner meetings
- There’s no separation of personal and work life. Your work life is your personal life. If you got pregnant, you have chance of getting fired. If you got a needy bf/gf? too bad that decreases your chances of getting hired or keeping your job.
- 9–6 is the common Korean work hours shift, but its not uncommon to see people working until 9pm, 10pm, midnight, or even 1–2am. Working weekends is normal too.
- Its frowned upon to switch companies. If you have too many companies on your resume your new employers might question your loyalty and refuse to hire you.
In my experience meeting Japanese and Chinese people, it seems Japan work culture is very similar but maybe not quite as intense as Korea (90% as intense?) after all Korea’s strict hierarchical work culture comes from Japanese work culture.
In contrast Chinese work culture seems more similar to American work culture and they seem to have little of any of these things. Sure people work overtime in China too especially in cities like Beijing or Shanghai but I think overall Chinese work culture is more flexible and loose.
