Thread: passed over on job promotion because of menopause

I was told by my manager today that another co-worker was getting a promotion that was available at our office. I was sort of surprised by this as I have been lead to believe for 3 years that when the position became available I would get it. (A little work history, I have worked for the company for almost 10 years. I have advanced up through the company with no problems before. I have worked at 4 different locations within the company and have been at this location for the last 3 years.) A co-worker, we will call Teresa, has been with the company for roughly 3 years and is younger. She is about 25 and I'm 40. She is always underfoot, and everyone can see her kissing up to the manager. Well, today I was told that I was being passed over this time but that I haven't done anything wrong and I do a great job. Also, I was advised that I had the better knowledge of the job and I was appreciated. Well, I asked why the decision was made in this matter and what I could do for future advancements. This is was my manager said, "You have been going through alot for awhile now and I know you have been having hormone issues and that they have changed your meds. I just feel that your attitude has changed." What?? I asked if I had been rude, a (edit), or any other number of things. I was told no. You do a great job, it's just you don't have the same attitude as before this started. My manager is a woman and she is roughly 10 years older than I am. I was shocked by this. She insisted that I was to understand her side of the decision but I just cannot swallow this. I work hard and I work hard at handling the symptoms of menopause. I feel so confused and cheated. Well, I just needed to vent but I can't see how this is an valid reason to get booted.
