The first amendment has never protected harassment, libel, slander, threats, or other such forms of harmful speech. It's not a "I can say whatever I want, whenever I want, with zero consequences" get-out-of-jail-free card.
But it did protect from banning words. Until now, at least in New York City it doesnt.
Intent is required for harassment. Using a word you dont like doesnt itself prove intent, especially when that word is the definition of an object. That object being an immigrant who has entered the country unlawfully.
This is literally just saying "for those of you who haven't figured it out yet, telling coworkers to go back to their own country is generally going to constitute harassment." It has always been harassment, it's just become necessary to spell it out thanks to a bunch of racists that have been emboldened by Trump.
Completely ignoring that my entire point was about illegal alien and not go back to your country I see...
