Working with migraines day in and day out.

I work for a health insurance company which I work in the call center part. I started there last Aug.07. I had my first episode with migraines in Dec. 07 while working during what they call open enrollment. It took me down for a month. When I came back to work they refuse to accommidate me in anyway at first. Told me that if I liked my job to deal with it. They explained that they couldn't accommidate me because then they would have to do it for others. I think that is not right in any case. Since each case is different. Now, they are offering people to go home and work out of their homes. But, with the metrics that they hold there is no way for me to go home and work. Because of my migraines my metrics are always down because I have to take a little time off the phones to get the migraine under control between calls. I have spoken with my supervisor which in way I think she does contribute to some of the really harsh migraine eposodes. She is always screaming about her metrics. I asked to be moved to another team by higher management and was told could not accommiate that either. I am stuck with the same superviser who just doesn't understand. I am in the process of going to HR and seeing what they can do for me. Since it is has been almost a year now and the supervisor is not being accommiating by any means. I am just wandering if I should just leave my job.

Anyone out there has any advise please share.  I could really use some support.

Sincerely,

Tracy
