This study demonstrates that despite promotional discrimination favoring females in a female-dominated workplace, such females likely have reduced tenure compared to men. This delivers a significant difference in gender balance within upper management. An Australian not-for-profit organization's Qualtrics survey provides 113 respondent demographic data sets, or 56% of the potential respondent pool. Females are typically promoted significantly faster than males. However, while males are promoted slower than females, they remain longer in their tenured positions and ultimately move into upper management. Why women choose to leave an organization at higher rates, notwithstanding their promotional advantages, may indicate family child-raising interruptions, in-house personality clashes, or possibly deeper gendered biases within the organization - such as a lack of fulfilment and a greater predisposition to suffer negative workplace conditions. Hence, further research in this area is advised.
