Did they tell her she was fired?
I didn't see that in the ruling, but perhaps it was left out.
And you may not like that it's up to the employees to follow policy, but it is, and if they don't, the accommodation may not be ready for them when they return to work. I work for a large federal agency, and we have two lactation rooms in our main building. Employees wishing to utilize either/both of the rooms have to fill out and submit paperwork 10 business days prior to when they need it in order to gain access credentials. So while you may not like that the employee has the responsibility to follow policy, that's the way it is. Same with maternity parking spaces where I work - pregnant employees can't just drive in and park in a space, they have to fill out paperwork and get a hangtag to park there, or they'll get a ticket.
