I understand what you mean? School owners should treat teachers repectfully and fairly. But what I mean sometime the so called teachers don't know how to teach kids, although they have teaching certificates. Fairly speaking, it's much easy for an English native speaker to introduce the content of the book that kids are learning, but the important thing is how do you make kids like listening to his/her introduction of the content. My school has never treated ESL teachers unfairly but friendly and repectfully. what we need is teachers who really know a little bit methodology. Don't know how can I find and invite.
