One focus of gender equity policies in universities has been the creation of ‘retention’ part-time work for professional staff, which allows employees to move between full-time and part-time hours at their request. This paper examines whether such ‘good’ part-time jobs can contribute to or at least not impede women’s career advancement. The paper examines the correlation between job classification and part-time work, and whether a period of part-time work acts as a significant ‘brake’ on a woman’s career trajectory. This study uses data from the 2011 Work and Careers in Australian Universities survey. Part-time work is used extensively by lower-classified women, but rarely by those in higher classifications. Part-time work stalls career advancement compared to working full-time, but this brake is reduced if a woman transitions back to full-time work.
