If not TESOL, then Cultural Education for you!
According to Brian in Jeollanam-do, a proposed law may require English teachers to undergo cultural training. Brian has good points about the article and the issues, so I’ll not comment further except to say this: A good number of foreigners I’ve met during my tenure here, some I even call friends, have desperately needed some form of cultural training. Or at the very least some manners classes.
