Koreans have some "hacks" to get around this (age-based) social hierarchy: 1. Some workplaces use English names (and even English language) so co-workers can speak/refer to each other without using the social hierarchy constructs built into the Korean language. 2. Social (partnered) dance clubs go by nicknames for the same reason. Even though I dance with them on a regular basis, I don't know most of my dance friends…
This is intended but didn't work as such, because wording only constitutes a small part of the whole social hierarchy.
