>What if I'm hiring someone specifically to work at a Spanish language news outlet?

Having actually worked at a Spanish language news outlet before (1 of 4 tv and radio stations in the office I was doing IT help desk work in), I can tell you that every single employee spoke English somewhere on the level of very good to near native fluency. As it turns out, knowing English (or the native language of whatever country you're in) is an incredible value-multiplier for almost every job position imaginable.

As far as language issues at my current job goes, it turns out once you hire a manager that speaks both Hindi and English (or Marathi and English, or Bengali and English, you get the picture) it doesn't matter much if the H1Bs he hires barely speak English because he can just start shouting at them in Hindi if they don't understand (even if several native English speakers are in the meeting too).

Again, this is a hiring issue, not a legal one. You want to make it against the law for your boss to hire bad managers?
