To call out one of my workers for whispering

[Wingbackchair]

One of my workers is very good but i often walk in on her whispering with others in the staff it stops when they see me. I think it's about things I've said or have just happened at work. Should I call her out on this or just ignore it

Sometimes I walk into the staff room and it seems like people are whispering and then stop when I walk in. I’ve also been there already when the whispering stops for someone else. It usually stops to see who is walking in so it might not be you they were whispering about.

I usually make a jokey comment if it happens to me.
