Based on my past experiences while working for Yuncheng IELTS,I have no choice but to side with what Sunny has said,bar her assessment of the good doctor as being considerate,sth I'm not in a position to comment on.
Furthermore, up to now I have observed that there have only been a few FT's who have felt strongly enough to post derogatory remarks from time to time on this board re their experiences while working for the good doctor,though in recent years a total of at least two dozen FT's teaching there on one-year contracts have chosen to remain anonymous re the pros and cons of working for the aforementioned boss.
Like me,ask yourself why only a smattering of them have seen fit to berate the company online.That's why you should take sides with the silent majority.There is nowhere near enough evidence to justify Yuncheng IELTS being on a blacklist of 'crap schools'.
