Yesterday was a bad day

Other than finding out that I have my Green Belt test...which isn't too much of a bad thing, as this time I am feeling fairly confident.

Here is my situation.

General: I am working at a Hagwon who is owned by a gangster who cares only about the money.

1) I am working in boring Gunsan.
2)hagwon has 15 or so teachers, 5 of which are english teachers, I am the only foreign teacher. 3)the numbers of students went down, but have now gone back up because my boss advertised again...claiming that there are 3 foreign teachers working here.
4)The teachers (korean) are leaving as they cant stand the director.
5) the kids are scared of him
6) his english is appalling and expects me to have another teacher there to translate if i want to talk to him (that is if he can be bothered).
7)he does not like the teachers to eat anywhere in the building inc the office (though we ignore him).
8.physical punishment is administered by all teachers, but with some level of aggression by the boss.

More specific.

1) he never has time to chat wth me, neither does he make time, so anything that is bothering me cannot be resolved in a more gentle manner.

2)i teach 8 40min classes in 6 hours ie no break, 5 min between each class to walk from one classroom to the next.

3)My contracts states that i should have 8-12 students per class. in reality in my middle school classes I have 25-30 rowdy teenagers.

4) He uses physical punishment on the students, uses half a snooker cue and beats them on the hand or accross the backside in an aggressive manner.

5) He has told the Korean teachers not to talk to me. Most of the time they stick to this.

6)when I first arrived he tried to take my passport and my immigration card off me. i refused. He tried again. i still refused.

7) he has me working for his friends school, which I have now heard for definate that is illegal.

8)yesterday My other boss at the other hagwon punished my 16 year olds right in front of me by violently hitting them across the backside with a wooden spatula. 2 of the girls were actually well behaved; i tried to stop him from hitting these two girls. he understood but ignored me. his reason for hitting them was ' if i dont hit them the other students wont play with them'. I told this man exactly what I thought of his actions.

8)both directors always say that it is korean culture to hit the kids, but Korean friends tell me that it is against the law

9) If i want to break my contract I have to forfeit a months pay and stay until he finds a replacement.

Yesterday, following the incident outlined above, something inside me snapped. If my situation is the Korean norm, I wouldn't mind so much, but as it turns out it is not.

I really want to get out, but how? I dont want to leave Korea as i am here to travel. this is a once in a life time opportunity. I could have a short contract in Seoul, but this means
1)permission from immigration-easier said than done
2)letter of release from my boss-not obligitory.

Somebody has suggested a midnight flight, but I really dont want to end up on immigrations blacklist...so many foreigners have ended up there purely by accident.

I have made the first step by seeking advice from the efl-law website
