When I moved from the Netherlands to this country in 2004, I was first employed as a conversational English lecturer and teacher at one of Northern Bangkok's universities for 4 years. My students consistently ranked highest in language proficiency for 4 years, even above those thaught by my native English speaking colleagues. I was even put in charge of teaching other university personnel English skills. Additionally, I was managing the university's English language website, writing and editing exams and courses, and even taught German and French. However, in 2008, I was unceremoniously dismissed for not being a native English speaker, and therefore was deemd unqualified to teach, by the new head of the language department. Fun fact, this new head's students had ranked lowest for the last 4 years, but she assured me it wasn't a form of revenge, just policy.
To make a long story short, I can't to always have a little smile on my face when I read these kind of articles, in which time and time again is stated what I have known for over 15 years. It's the system that causes this.
