Teachers are a commodity
Teachers are a commodity in Thailand, like bread, rice and chicken. By treating us like we’re replaceable, they can avoid paying much. The only way I know to counteract this is to focus on every option, even those you may normally not choose. There are more than just schools that need English teachers. There are more countries than Thailand. Universities, language schools, corporate training are a few of the local choices. There are a ton of other countries too that pay the same as Thailand does, many that pay double or triple too. I worked at a public school in Phuket that payed peanuts. They punished me after I left by giving me terrible references, despite me leaving between terms, according to my contract. I enjoyed working at schools, but most often, they don’t understand give and take - only take.
