>Which mean she can do pretty much any office job fine.
replyHonestly, I doubt it. If you show up to an interview of "any office job" with "epilepsy and paralysis on one side" nobody will hire you simply because you won't be as productive as those without such disabilities.
Also, "epilepsy and paralysis on one side" is the legal medical diagnosis, but in practice the impact can be much greater, especially with age, which is why ageism is a thing even among people who are legally in full health because in practice your body isn't the same like when you were 19-25.
But given that they already hired her, if she's going at 30-90% speed depending on task then it should be very easy to keep giving her tasks. And she can practice things like one-handed typing to improve the average.
replyShe doesn't need the equivalent of "moving paper from one room to the next". She lost some number of dollars per hour worth of productivity, but it sounds like she was still capable of being reasonably productive.
