I have made it a point to inform my superiors and Human Resources at work. I work for a very large company with established policies & reasonable health insurance. I learned that our HR director has experience with PD (a relative). She has been extremely helpful in explaining policies, advising on strategies, etc. I am pretty high up in management myself, so I only have to worry about a couple of layers above me, of whom some are long standing personal friends, so I knew I'd be safe. I also figure I'm safer from criticism etc. if it's out in the open. I have let my clients know too, as appropriate. This is just my experience. One has to consider one's own employer's likely reactions and caution may be proper.
