Ventajas
You are with one kindie class for the entire year. Lots of work but just concentrating on this one class makes things easier. Management will also try to schedule the best vacation times, even if that means losing out on other holidays throughout the year. It's not great but it's more than other hagwons will do for their employees.
Desventajas
MWF schedules are more packed with work than T and TR ones. The work is not hard, but there is a lot of it. There are no computers in the rooms so if I wanted to show my students some multimedia resources I had to use my phone or laptop, which was annoying. Also, most of the other teachers were fine at their jobs but had lackluster personalities. That's just an opinion but it pushed me to not stay for another year. Professionally this company was fine, but socially I could not stay here longer than I had to. At least you don't have to worry about this company going down anytime soon!
