I’m an RN in a large hospital near Seattle.
Isn’t there a nurse shortage throughout the nation? If so and if your lefty boss wants to give you static ... move. I’ll send you some RN openings.
My advice? Do your job to the best of your ability each day. Serve God. Don't allow these yahoos to move you away from any place or thing that God has placed you. Silence says a lot. Move on focus on work. If you are bated continue to focus on your work. That is what you are paid for. If something happens and you lose your job, God will provide. You just do your job of being the best RN you can be.
If you live near Seattle you best just bite your tongue and avoid the topic of politics. Just pointedly change the subject if the woman makes any political comments at all. If she brings up the language policy again, tell her that it isn’t political, it is a safety issue and a matter patient confidence. ( No one wants nurses or aids speaking a language they cannot understand, while they are stuck in a hospital bed).
