What you like to call "rubbish pretend schools" oh please! You wouldn't know a decent school if it smacked you in the face! You think ESL exams, internationally used exams to measure English ability for education and employment criteria, are "scams". You think an oral exam administered and created and graded by yourself is all the assessment your students need! You wouldn't know a CEFR syllabus from Adam!

Criticising what textbooks and what syllabus, without even asking which are being used, is ludicrous. The only reason syllabus/books would be unsuitable for a class is if the students haven't been accurately level tested, in which case it is a problem with the class, not the books or the syllabus.

You teach conversation classes, Silverboy. You haven't got the first idea what is required for teaching ESL from beginner to advanced level! As this entire post proves.

"Frustrating to know you are providing crap classes" the only person responsible for the standard of a lesson is the teacher. If the text book you're given isn't great, supplement it. That's your job. You don't just teach directly from the book and then bitch about the materials. Take some responsibility yourself! You are the teacher, the buck stops with you. Now I suppose you'll say "why should you waste time gathering additional materials" because that's part of your job, because if you truly cared about your students you'd be doing it anyway.

If the school is truly doing something unethical, then it would be helpful to know what it is. Then actual advice can be given, rather than just randomly bashing private schools. Especially considering the OP doesn't know what classroom management is or involves, so his ability to judge what is or isn't educationally important for students may not be that reliable.
