This case is neither particularly exciting, nor complicated.
Maria J. Collazo-Rosado worked for the University of Puerto Rico, heading up its student tutoring department. She suffers from Chron's Disease, which causes inflammation of the intestines. You're not a doctor, and neither am I, but that basically means she runs to the toilet a lot and has to have frequent visits with a doctor.
UPR had a pretty strict attendance policy about using time cards, one which she repeatedly failed to follow (ostensibly because of her condition, though she even failed to text or email when she was going to be late, as required by UPR). She might have had a fighting chance at a claim except ... she failed at her actual job, nuking any possible claims of retaliation and pretextual termination.
