I am about to sign a contract to teach english in S. Korea. The school that offered me the contract has only been open for 6 months. They have offered to pay me 2.1m won which is pretty good considering I only have a BA and no esl experience.

In the contract it states that I will be paid the salary of a month on the last day of the following month.

My Questions:

How often do schools go out of business?

What is the current tax rate deduction in S. Korea?

What other deductions are there and is pension?

When I asked to speak with the current foreign teachers the director told me that it would not be possible, is that normal?

How easy is it to find a job if you are already in Korea?(just in case)

Please HELP me I am supposed to sign with 24 hours, any advice anyone has for me would be appreciated thank you.
