The woman claimed disability and racial discrimination, as well as constructive dismissal, in her suit against Leeds Metropolitan University, Sky News reported Thursday.
She told the Leeds Employment Tribunal that colleagues would regularly make sniffing noises and "bowel jokes" while in her company.

A Leeds Employment Tribunal spokesman said the panel's three judges dismissed all three claims in the suit.
