This article summarizes the effects of the Howard Government's `Work Choices' amendments to the Workplace Relations Act 1996, based on qualitative analysis of its impact on 121 low paid women workers. The main effects of the regulatory changes are on job security, income, voice, working time and redundancy pay. The analysis draws attention to the nexus between protection from unfair dismissal and security of working time and employee voice: many of those interviewed in the study had lost access to protection from unfair dismissal and as a consequence could no longer effectively influence their working hours, or request flexibility. Employer prerogative was perceived to have strengthened in many of their workplaces, with consequences for the intensity of work. The analysis suggests that improvements in minimum standards and job security are vital if low paid workers like those included in the study are to exercise voice over working time and avoid significant deteriorations in their pay and conditions.
