Wow. I also worked for Yes English Academy in Ok Dong, Ulsan but had nowhere near as bad an experience as those reported on here and neither, I think did the other teachers working with me at the time. Although the school was not perfect, it was at the time considered to be one of the best to work at, the apartments were new and much above the standards of other teachers apartments and the school was well-respected for its teaching levels, most Korean teachers were excellent at their job and although a little lax on the teaching methods for foreign teachers (little training etc) this is typical of many schools around Korea. So too, is keeping hold of passports for a beginning period in order that their outlay for plane tickets is fulfilled. I really hope this school hasn't changed so considerably since the time I worked there, but suggest readers exercise some caution over taking these complaints as word.
