If your teaching hours are low, you may be asked to spend some time in developing material and researching programs for the institute. The premiums are generally quite low compared to the US for similar coverage, and the costs may be paid entirely by your employer or split with your employer. Health care costs in Korea are much less expensive than in North America. Unsused sick leave cannot be taken as vacation time, and is usually not compensated. The employer will pay the rent for the apartment but the teachers are responsible for the heating, electricity and water bills.
All apartments come with a laundry machine, kitchen table and chairs, beds, desks, and ward robes.
You will receive about 5-10 days of vacation and you will receive all other Korean national holidays off as well.
