Interesting but not representative

The Australian Council of Trade Unions (ACTU) released the results of its latest occupational health and safety (OHS) survey. In past surveys respondents have been trade union members. This survey was opened to non-union members, but to what extent is unclear but this has not stopped the ACTU speaking of the respondents as workers rather than workers who are all union members.

This differentiation is important. In the 1990s when union membership was much larger, the argument that the survey results were representative of Australia’s workforce was stronger although still debatable. Representation is harder to claim now with union membership being well below 20% overall and below 10% in the private sector.
