Labor bought by some of the union movement's worst: AUSTRALIA'S most militant union has been quietly underpinning the Labor Party's finances, donating more than $9.1 million since the start of the Cole royal commission [a decade ago], placing intense pressure on the Gillard government over the future of industrial relations policy... In terms of total donations, which include state and national offices, the [Construction Forestry Mining and Energy Union] is second only to the powerful shop assistants union... Victorian Labor is facing growing internal concern about the influence of the CFMEU over state Opposition Leader Daniel Andrews and whether the association could damage his leadership. The CFMEU and other unions will launch their campaign against construction giant Grocon today at the site of a city wall collapse at a future company development where three people died. The decision to politicise the accident site has been savaged by business and the Napthine government but Mr Andrews has refused to say whether he supports or opposes the march. Some background: Labor promised two elections ago to scrap the Australian Building and Construction Commission, created by the Howard government after the Cole Royal Commission identified widespread illegal industrial action. The ABCC was well-armed and tough. In its last year, the courts hit unions with more than $2.5 million in penalties... But the CFMEU demanded Labor get this policeman off its back... And Julia Gillard (whose former boyfriends include CFMEU national secretary Michael O'Connor) delivered, last month replacing the ABCC with the Fair Work Building and Construction agency.
