Labor leader Bill Shorten won't interfere in wage negotiations between employers, their workers and trade unions.
His comments follow a deal the CFMEU struck with big construction firms for a 15 per cent wage rise over three years, which Deloitte predicts could add between 5 to 15 per cent to the cost of Victorian state-funded infrastructure projects.
"I am not about cutting peoples' wages, I am not interested in trying to interfere in commercial negotiations between employers and employees," Mr Shorten told reporters in Darwin on Friday.
