As I mentioned in another post one of my co-workers lost his daughter this week. I have been asking around at work to see if anyone knows if we can donate PTO/sick time to the co-worker. I've heard of it being done other places but I don't know any details.

Have you done it or does your company do it? What are the limitations? (PTO but not sick time? Does it matter if you make less than the employee you donate to?)
