Also, I hope I don't sound cold, but if you don't want to be exposed to people who have infectious diseases, why did you become a healthcare worker or doctor? What did you think is going to happen in that job?
I don't see a problem with healthcare workers encouraging safer behaviors. Doctors certainly encourage people to wear seatbelts and motorcycle helmets. My orthopedic surgeon encouraged me to practice better ladder safety after he put my humerus back together with a plate and nine screws. Seemed like good advice to me.
Do firemen complain about fires? They too protect themselves the best they can and then go into the fire anyway. So too a medical worker has to protect themselves the best they can, and go into the fire. They're brave as firemen are. But there are risks.
Firemen advocate for fire safety. They go to schools all the time to impress upon children the importance of not starting fires under their beds when they are pretending to go camping.
Construction workers protect themselves as well with fall protection, masks, etc. But they still die at rates higher than the average public due to their occupation.
Construction workers advocate for safety too. They have their unions make construction companies adopt safety measures.
Tell me again why a healthcare worker can't complain about their patients doing stupid stuff, like not wearing a mask, or not washing their hands, or not social distancing, or gathering in large groups?
