Reading between the lines alerts me that the poster calling himself 'The Truth' is trying to dissuade foreign teachers from applying to EV Company for jobs. It also tells me that you are an employee or a former employee of IELTS School, but unlike him, you are not out to discredit EV.
I think you should cease replying to that whistleblower forthwith in order to exercise damage limitation regarding EV's good reputation.
I reckon you are a sensible bloke who appreciates the advantages of having a TA in class to manage the teaching in a positive way by disciplining naughty students and simpifying the teaching task through interpretation and translation. That other poster talks about greener grass elsewhere, but he fails to mention ease of teaching, which depends greatly on a TA!
All the very best to EV & IELTS Companies of Yuncheng!
