Heh. As I learned a couple of years ago during a very difficult period at work, it's actually no longer legal in the U.S. to require that a mentally ill employee get treatment as a condition of employment.

You can fire someone for not being able to do their job, but you can't say "get some help if you want to keep your job," about mental health issues or any other medical condition.

Yes, this seems profoundly ass-backwards to me, and I was the manager who eventually ended up having to do the firing.
