Thread: Useless Thai Assistant Teachers

I've been at my school 3 years. last year I had 2 great Thai teachers to assist me as the disciplinarians. Unfortunately this year one has left for another school, and the other has been assigned to the lower grades for reasons unknown to me. Now I have 1 Thai teacher who is so lazy she usually shows up 15 minutes into class, and walks in and out without any reason. She is retiring next year and obviously does not care. When the children act up and I look over at her and she's sitting there reading a book. If I ask, she will tell them to be quiet, but that lasts about 5 minutes. The sad thing is, she's the best one. The other one has some kind of emotional problems. She comes to school maybe 70% of the time, sometimes in tears. (depression I think). When she's in class, she'll sit there is a daze while the children run wild, then sudenly explode and start hitting them with a stick and screaming at them. The older children (P6) actually laugh at her. I feel complaining to the principle is starting a battle I cannot win, and the school probably knows how useless these 2 are, which is why they are being used for classroom monitors.
It does not surprise me that in a country where 30-40% of adult car and motorcycle drivers think it is OK to drive on the far edge of the wrong side of a divided highway instead of going around the block, you will have disciplinary problems in the schools, but this is reaching the level of making any effort to teach useless. Any ideas? Like I said, we have a good Principal, but starting a pissing match with the Thai teachers seems like I'm starting a battle I can;t win, no matter how right I am. Thank you in advance for any constructive suggestions.
