As a new mom, I've felt very lucky to have a workplace that makes no complaints about my need to pump and that has a room for that purpose. Unfortunately, that room is attached to the first aid room (which requires a key) and, today, I found a woman in the lactation space who said she wasn't feeling well and was trying to find a place to rest for a bit.
Since the room is specifically for lactation usage, I had no issues telling her that I needed the space and I let her know that I would be finished in about a half hour. I didn't want to make someone already feeling unwell feel unwelcome but I'm concerned about transfer of whatever is making her feel poorly to me and to my baby.
I'm generally not an overly germ-conscious person and I know that many women don't even have the facilities that I do... but is it unreasonable for me to talk to our administration staff about preventing people who are sick from being in the lactation room? I don't think there are any legal requirements that the room must be only for lactation purposes.
