Do not work for Gimpo Topia.
Also, do not work for Herald Kids in Gimpo.

These two schools are owned by the same owner, and his name is Alex Kim. He is a horrible boss to work for. All he cares about is money, and maximizing your work hours.
There are many reputable schools in Korea, so no need to sell yourself short to work for this greedy bastard.

A few good things about this school:
They pay on time
They are in good financial situation

BAD THINGS:
He will overwork you
He will make you feel like shit
He will under appreciate you.

I warn you! Do not work for Gimpo Topia. Do not work for Herald Kids in Gimpo.
