I work in a small office (5 employees). I don't wear my religion on my sleeve and don't feel the need to. One employee is Catholic and attends church regularly (I know way too much about her personal life). During the Christmas Season, she listens to Christmas music and puts a nativity scene at her desk. I can hadle the "Jingle Bells" but it really bothers me when Silent Night, or other music referencing Jesus comes on. And she doesn't listen to music the rest of the year.
I have approached her in the past about the music only, and she gets very defensive and makes suggestions ranging from "get a new desk/office" to "well I can barely hear it, how can you?" Last year I did approach our supervisor, but I don't think he did anything except to ask her to turn the music down. My desk is right next to her's so it's pretty impossible to avoid.
Any ideas? She and I don't have the best relationship to begin with, so the month of December is particularly difficult.
