Employment Minister Eric Abetz has warned the CFMEU that if they are not prepared to change their ways others will do it for them.

Senator Abetz told a building conference that Australia cannot afford to have an unproductive building sector and has flagged revised building laws.

He said in the light of recent corruption allegations unions continue to deny the undeniable.

“If they won’t do what is necessary to clean up their union then it will inevitably fall to others to do so,” Senator Abetz told the Master Builders Association of Victoria conference.
