Racist, and a way for management to know if workers are discussing unionization.

Not always, it’s also a politeness thing, it depends on context

I don’t agree. Forcing people to use a language they are less comfortable with just so others can eavesdrop has nothing to do with “politeness.”

It’s not eavesdropping lol. I worked a company that was primarily Chinese people at the head office and they made a rule of speaking in English for inclusivity.

The post references any usage of spanish as bannable. There’s a difference between workers speaking spanish with each other while someone who only speaks English is present, and workers speaking spanish with each other when nobody else is involved with the conversation. I also worked at a company with a huge portion of speakers that were uncomfortable with speaking English despite myself only speaking English, any attempt to ban their language would hurt the company.

Right? Hence context
