Example: several of my former coworkers are from Mexico, Peru and Argentina, meaning they share Spanish as a common language.
I used to practice Spanish with them, but my last charge (like a ward’s manager) would yell at us to stop it, use English only. She would get very angry really fast if she heard anything in a language she didn’t understand.
I find it stupid, because some of them would use Spanish to better explain to the new nurses how to do certain procedures, but maybe I’m missing something?
Work related? Sure, 100%. Everyone might need to hear what’s going on and if English is the dominant language that’s what should be used. Personal conversation? Fuck that.
If Spanish is the dominant language I would expect all business to be conducted in Spanish.
edit: but yeah, if someone needs it explained in their native language, for sure use it. In that case one should do both languages.
