When bosses are late with pay it is best to tell them YOU will be late to work. They hate this kind of pressure. Many Korean bosses lie all the time. Contracts are a joke. They are to control you and not them. The Labour Officers rarely help, even if you bring a translator so don't waste your time or breath. There are numerous bad reports of Korea on internet sites. No big secret. You are on your own. Bosses are just as bad to their Korean employees so don't feel singled out. Few Korean workers at hogwans ever get any pension or severance pay. Many are hired part-time and get no pay for holidays. If you come to Korea or China etc. you have to come for your own reasons (money, tourism, learning etc.) and bail out if conditions become unbearable. You might make some money (most do) and you might lose (especially if you let bosses walk on you). It takes a thick skin to get by here.
