This article considers the problems these women face in entering a previously all-male, 'front-line' occupation. The discussion focuses on (1) how well female officers meet the security demands of security work, (2) the nature of, and basis for, difficulties in relating to male co-workers, and (3) occupational socialization and advancement. Drawing on available empirical and anecdotal data on women officers in male prisons and on the more general prison guard literature, the intent is to present what is known about these women officers. A research agenda is offered to guide inquiry into the problems of the sexual integration of correctional institutions. (Author abstract)
