Bean Counters
If you know any expat teachers in HK (as I do), ask them about the erosion of their T & Cs over the years. In exactly the same way as airline bean counters have attacked our T & Cs, teachers & probably a number of other professionals, have been devalued.
If you know any teacher employed by ESF, ask them their opinion of their CEO. The comments will be stronger than comments by CX pilots about the current CX CEO. In fact the sheer contempt they have for their CEO has very scary parallels to some of the opinions we had of a previous CEO, initials DT.
