I taught English at Nakhon Phanom University for over two years. My salary was 28,000 Baht per month, and I often taught special classes for various groups in the evenings or on the weekends. Those special classes were paid at various rates: 1000 Baht per hour, 600 Baht per hour, 400 Baht per hour... down to 50 Baht per hour. One section of the university, the International Aviation College, likes to take the teachers' pay and keep it. That happened to me, to two foreign pilots, and it has happened to two Thai teachers who I used to work with. Classes for the IAC were especially well paid, if one could actually see the money. The two foreign pilots were "hired," but they were not given a salary because of "paperwork difficulties." They were told to keep working and wait for their salary to come. I watched one young man from New Zealand become desperate as he went months without pay. I believe he became penniless and had to depart Thailand. The xxxxxxxxxxxxxxxxxx, Dr. xxxxxxxxxx, who is now either in jail or is pending incarceration due to malfeasance, told me to work for 50 Baht per hour instead of the 400 Baht per hour agreed up in my contract. I thought it was kind of funny, at that time. Later he got into hot water for selling fake degrees and putting the money in this bank account. I saw four out of the five foreign teachers treated badly at NPU. As far as skimming goes, they had a trick for every day of the week and two for on Sunday. Class sizes were gigantic, but I did have some good students. I really tried to benefit those kids, to get them away from FaceBook a little and perhaps learn something. After the International Aviation College tried to keep 30,000 Baht of my salary, and after watching the administration at NPULI try to siphon a bit off of my other pay from additional classes, I simply went to the police in Bangkok. I got paid in full within 48 hours. I also quit. So this posting is a warning for anyone who wants to work at NPU. There is a history of malfeasance. Make sure to get everything written into a contract, to include all the details of the special classes as they come up. Don't take a smile for an answer. Otherwise, your pay is going to be a little lighter than what you expected.
