The National Tertiary Education Union (NTEU) is the only union working entirely in tertiary education around Australia. The union has over twenty four thousand members comprising of academic and general staff. NTEU maintains membership records at three levels, national, state and branch. The information collected includes gender, age group, employment type and work classification. In late April 2005, Higher Education Workplace Relations Requirements (HEWRRs) legislation was introduced by the Australian government. This legislation imposed restrictions on the interaction between the universities and the union and also curtailed an automatic involvement of the union in the resolution of workplace issues. The general area of interest lies in whether there was a significant impact on the NTEU membership density following the introduction of the HEWRRs. Time series analysis techniques such as de-trending to achieve stationarity and autoregressive integrated moving average models are· applied to the proportion of the NTEU members to Full-Time Equivalent (FTE) staff before the introduction of the HEWRRs legislation. The impact of the HEWRRs is measured using intervention analysis. The overall analyses for the whole of Australia show a significant immediate impact as a consequence of the legislation. Some individual branches are unaffected. Gradual or no impact of the legislation for the divisions was observed.
