Is it discrimination to only hire teachers from "certain native speaking" countries?

Yes, I have linked it a lot too. I was among one of the first.

Article 62

Any person shall not discriminate against people residing in the Taiwan Area on the basis of nationality, race, color, class and place of birth.
Any person whose rights are trespassed due to the discrimination mentioned in the preceding Paragraph can file a complaint to the competent authorities on the basis of the situations of the trespass, unless the matter is regulated by other laws otherwise.
The competent authorities shall enact regulations that govern items, requirements for filing a complaint mentioned in the preceding Paragraph, complaint procedures and the composition of a review committee.

Again, if they said for example “no blacks” or “whites only” or “no Mexicans” then that would be considered discrimination in the eyes of Taiwan’s laws. Saying: * Australia.

  • Canada.
  • Ireland.
  • New Zealand.
  • South Africa.
  • The United Kingdom (England, Scotland, Wales, Northern Ireland)
  • the United States.

You are more than welcome to file a complaint and have them spell it out.
