how will i address my korean co-worker?

Question

As an in-team trainer, I will be conducting the training for a Korean new hire. As I am 3 years younger than she is, how will I address her? Do I need to use ~ ㅂ니다 form everytime? Or will ~요 do? How do I call her name? ~~씨 or 김 양?

Having stayed in Korea before, I understand that Koreans place great importance on relationships i.e. seniority at work.

In this case, I have a higher position than her. But she is older than I am. So, which one should be followed?

Answer 1

In this case she is the foreigner in our country-use the appropriate western polite address and let her begin to follow the culture she is in.

Answer 2

If her name was for example Kim, Chong Cha...Kim being the family name...Chong being the first name...So Miss or Mrs Kim or Chong if she prefers.
