What state are you in? I think it’s important that you raise your concerns with HR and (at minimum) the manager who you report to directly. The benefits of widespread mask wearing indoors are scientifically proven and easily understood. The type of company that would dismiss such concerns is not a place I would want to work RN. We are all wearing masks in my office and eating at our desks rather than congregating in the break room. We do share some contact surfaces, such as copier, fax machine, microwave, refrigerator, but trying to disinfect as much as possible and keep exposure to a minimum. There are some good videos and images that explain the benefits of wearing masks indoors in basic non-scientific terms that you can share with HR and management if they play dumb.
