Welcome to KoreanClass101.com!
What should I call you? Do you have English or Korean name? I guess you have both.
My name is Tim! Call me Tim!
First, it's very hot in Korea right now, very humid! be aware of that!
Second, do you know where you are going to work for? What kind of work? I guess you are going there to teach English. If you let me know where the office is located, I might give you some good tips.
Third, there are tons of private English schools in Korea. If you don't like your work or the employer abuses his/her power over you, just quit! There are better places for you to be able to teach English with good working condition.
Last, I know you are Korean-American, which means you would know both cultures very well but, knowing in your head and living actually in the place is quite different. If you feel stressed or discouraged by any reason, come here and leave message to me or to many friends around here. That would help you relieve your stress.
I would do my best to help you out not physically but mentally since I am not in Korea now.
Your friend, Tim
