Background: I have some issues with my back stemming from muscle tension that result in horrible back spasms that put me out of commission for at least 24 hours. I recently started getting massage therapy for the spasms and it is helping.
One of the issues causing my back problems was my horrible office chair. It had no arms and very little support, so I never sat up properly in it. My massage therapist cites that as probably the biggest contributer to the problem. After having a particularly bad spasm over the weekend, I went to my boss on Monday morning and requested that they order me a new chair, similar to one that another woman in our office (who also reports to my boss but is in a different department) has. Instead, my boss told me to take hers as she is only there three days a week and often out on sales calls, while I am in the office five days a week for most of the day. She told me to tell the woman that she (my boss) had told me to change chairs if there was a problem.
On Tuesday the woman came in and was a bit put off by the fact that I had swapped chairs. When she mentioned it to our boss, she was told that because I am here full time and she is not, I will get the use of the chair and they will order her another one, but for now she can use my old chair or another chair that has arms and more support, but isn't as good as the one I am now using. She chose that second chair, and made a few snarky comments about it to me, though I ignored her.
Well, she has continued to make snarky comments about how I stole her chair, asking how it is and if it's comfortable for me and how I live with myself knowing I stole the chair. Yesterday I smiled and told her I was quite happy in my chair, but she's doing it again today and I'm getting to the end of my rope. I know she is bullying me to get me to let her use the chair but hiding it through humour. Our boss is away now until Monday, so I am unable to bring it up with her.
Is there anything I can say to make her stop, or is it best to just ignore her? My evil side wants to go off on her, but I know that's not the right course.
