The increase in pension eligibility ages in Australia, as elsewhere, throws into relief the consequences of gender inequality in employment. Because of career histories in lower paid and more insecure employment, a higher percentage of women than men are dependent on the age pension rather than on superannuation or savings and investments, and so will be disproportionately affected by deferred access. Yet, fewer women than men hold the types of ‘good jobs’ that will sustain them into an older age. Women are more likely to be sequestered in precarious employment, with reduced job quality and a greater potential for premature workforce exit. This article counterposes macro-level data drawn from national cross-sectional labour force statistics and the longitudinal Household Income and Labour Dynamics Australia survey, with case study analysis, based on interviews with 38 women in midlife insecure jobs, in order to identify the types of life course and labour market barriers that contribute to women’s reliance on the pension and the systemic disadvantage that will render them particularly vulnerable to any further erosion of this safety net. The analysis moves between this empirical evidence and a discussion, drawing on the theoretical literature, of the failure in equal opportunity endeavours over recent decades and what this means for later life workforce participation for women.
