Although librarians in CUNY had achieved Faculty Status by 1946 and Faculty Rank in 1965, they were still never put on the Faculty Calendar with the Summer (or its equivalent) off. Professional Reassignment leave for library faculty was added to the contract in 1978 as a two-week research leave, and it has since expanded to a maximum of six weeks. However, as Professional Reassignment leave increased, the amount of annual leave for new librarians decreased.
