I only say this because I know you guys would never take *unfair* advantage of it, but:
The Americans with Disabilities act prohibits employers from dismissing Rho on the basis of her disability.
This guide explains what is basically covered and how to get more info from a local office.
My opinion is that the ADA is an ugly scar on the employee/employer relationship, and frankly I doubt it does anything good for disabled people. Sure, the intent of the law is to protect the disabled and to make sure they get equal opportunity and fair treatment.
But in the real world, things never work as the lawmakers say. Instead of just dropping Rho they may try to build a file against her, or avoid hiring her entirely. When the govt attempts to improve things for people via the law, it's the people who can understand the law (ie,
lawyers) and USE the law that benefit... which is not generally the employee. Unless the employee has been to a year of law school, or enjoys reading case law in their spare time...
BUT, that said, if people are being dicks about it for no good reason, then I say use whatever you've got. If this really is just a case of ignorant prejudice, then fuck 'em, they deserve it.
Legally, then, your best bet is to NOT disclose at first (it's illegal for them to ask), and then disclose one minute after hiring.
