The transcripts from the Royal Commission into Trade Union Corruption should be compulsory reading for every Australian employer (and voter for that matter).

The evidence being given by witnesses appearing before the Commission provides an illuminating – though terrifying – insight into the world of trade union thuggery, intimidation, and illegal activity.

Recently, the Attorney General, Senator George Brandis, approved a 12-month extension of the Commission’s inquiry, allowing the Hon John Dyson Heydon AC QC until December 2015 to hand down the Commission’s final report.

Senator Brandis announced the 12-month extension following his receipt of a letter from the Hon John Dyson Heydon AC QC which advised the Minister that:

"The inquiry thus far has revealed evidence of criminal conduct, which includes widespread instances of physical and verbal violence, cartel conduct, secondary boycotts, contempt of court and other institutional orders and the encouragement of others to commit these contempts.”

Mr Heydon went on to inform the Minister that some trade union officials:

“…appear to regard their unions as having immunity not only from the norms and sanctions of the Australian legal system but also from any social or community standard shared by other Australians."

Mr Heydon’s observations are certainly no surprise to anyone who has ever represented a small business owner against a union. My experience with union officials – with some notable exceptions – has been overwhelmingly negative.

But, unsurprisingly, unions and the Australian Labor Party have opposed the extension granted to the Commission.

Surely the people with the most to gain from a cleaned-up, law-abiding, and genuinely-respected union movement would be the unions themselves and their political wing comprised of former union officials now elected to our nation’s various state and federal parliaments?

If only the leader of the ACTU, Ged Kearney, or ALP leader Bill Shorten, could speak as frequently and passionately about the need for everyone in our nation to respect the rule of law as they do about matters that promote their own self-interest.

Mr Heydon’s discovery that many unions simply ignore the law should be a grave cause for concern for every law-abiding employer. But far more concerning is the lack of interest or outrage being expressed by those in the union movement who continue to live in an imaginary world where unions can do no wrong.
