Calypso Nash is a full-time postgraduate student at another college to whom we offered a small amount of casual work on an occasional basis as a library invigilator. She was not employed by St Hilda’s as a librarian, and both the Librarian and Assistant Librarian are still in post. The role of an invigilator is to maintain quiet in the library, or, if not able to maintain quiet, to refer incidents on. As this role was not performed, the Librarian decided not to offer Calypso further casual work. She has not appealed against this decision.
