I got some rather non-committal feedback from the Labor Ministry today. They said such situations would have to be evaluated on a case by case basis, and could be reported with company details to local gvmt. labor or social services units.
“Specialized and technical work” covers many jobs, but if a company or other entity runs an unregistered or incorrectly registered de facto buxiban (according to the legal definition), the government can fine it to death.
I sent an inquiry to MOE about the restriction nationalities of English teachers on recruitment announce by public schools. They clearly said the requirement is a passport from a country whose official language is english and it is not limited to 6 or 7 countries. They also said MOE should be responsible to supervise local governments so they will ask to the local authority to investigate the situation and do what they should do.
So, I think limitation of nationalities on the ads of English teaching positions on this forum should be removed.
MOFA still not putting nail in the coffin on which nationalities are kosher or not for teaching English here.
I take India, Philippines, Singapore, Malaysia becoming OK-ish now?
What about Nigeria, Pakistan, Jamaica, Belize, Ghana, Liberia, Kenya, Uganda, Tanzania or Gambia.
Referencing wikipedia, quite a lot countries that officially adopt English as their official language.
