The general rule of Thumb is don't tell your employer.

Although, before I started my current job, I made a point to tell my boss, the CEO about being bipolar. He's a friend of mine, and I wanted him to know that I'm much different now (on meds) than when we previously worked together (before meds). Although, I'm lucky enough to tell people since I'm a senior executive, which is why I started my Bipolar blog.
