You don't even have to give 3 months notice. The contract states, 3 month OR $5000.00USD payment in lieu of. (Notwithstanding that first year requirement as stated by Bus Driver) You can give them 10 seconds notice if you really want AND keep within the agreement. Don't expect them to ever hire you back though ... and that would be very understandable on their part.
Haejangkuk ... You do have a bit of a chip on your shoulders don't you? You're still using that silly little rant about the meal tickets. Get some better ammo.
I would like to ask you though, why do you think the Korean 'belles', (as you refer to them) are choosing the Expats? .. Are they looking for something a bit BIGGER? a FULLER life? .. maybe?
