I’m afraid so. I refer you to this question, which will explain why:

The person in question has managed to completely kill the holiday spirit at my workplace and has left everyone either angry, upset, frustrated or grouchy. She got my boss really stressed out and in turn he was very short and pissy with me for the past week or so. She even tried to convince all of us to agree to call off the firm luncheon because she “just couldn’t deal with it.” We still held it, but all the fun was sucked out of it. Now that I’m on break until after Christmas, I’m trying to regain my spirit by baking, finishing up shopping, listening to holiday music, etc. It’s working, but I was really looking forward to Christmas until she crapped all over everyone’s mood and it’s been hard to get back in the mood. Our poor receptionist got stuck at the office yesterday (our last work day before Christmas) until 6 p.m. fixing her stupid mistakes and had to wait for the late train, getting home hours later than normal. :(
My SO is out having dinner with his co-workers and I’m baking ginger snaps. When he gets here and I can have some time with him (I work days, he works nights and we don’t get much time together) I will feel a lot happier.
