In the context of population aging, the U.K. government is encouraging people to work longer and delay retirement, and it is claimed that many people now make “gradual” transitions from full-time to part-time work to retirement. Part-time employment in older age may, however, be largely due to women working part-time before older age, as per a U.K. “modified male breadwinner” model. This article therefore separately examines the extent to which men and women make transitions into part-time work in older age, and whether such transitions are influenced by marital status. Following older men and women over a 10-year period using the English Longitudinal Study of Ageing, this article presents sequence, cluster, and multinomial logistic regression analyses. Little evidence is found for people moving into part-time work in older age. Typically, women did not work at all or they worked part-time (with some remaining in part-time work and some retiring/exiting from this activity). Consistent with a “modified male breadwinner” logic, marriage was positively related to the likelihood of women belonging to typically “female employment pathway clusters,” which mostly consist of part-time work or not being employed. Men were mostly working full-time regardless of marital status. Attempts to extend working lives among older women are therefore likely to be complicated by the influence of traditional gender roles on employment.
