Opposition Leader Tony Abbott says his industrial relations policy will protect the pay and conditions of workers, and offer them access to flexibility arrangements.
Mr Abbott said the coalition's workplace policy would "retain and improve the Fair Work Act".
"We want to protect workers pay and conditions, we also want to maximise their opportunities to get good jobs," Mr Abbott told reporters in Sydney.
"The only people with anything to worry about from this policy are dodgy union officials and their supporters."
Mr Abbott said the coalition would "stamp out" union corruption by re-establishing the Australian Building and Construction Commission and putting in place greater checks on registered organisations, such as unions and employer bodies.
"There has been example after example of rorts, rackets and even corruption inside some important unions," Mr Abbott said.
He cited the cases of Health Services Union officials allegedly misusing member funds and the Independent Commission Against Corruption hearings in NSW.
"We need the same high standards of governance in unions as we expect in companies and that's why part of our changes will be to ensure that dodgy union officials face the same penalties as dodgy company officials," he said.
The second formal policy to be launched by the coalition ahead of the September 14 election would also ask the Productivity Commission to review the longer term operation of workplace laws.
The Coalition would make the commission's recommendations public. "We want to see wide public debate of those recommendations," Mr Abbott said.
"Any recommendations that the coalition supports would be taken to a new election for us to seek a mandate for them."
Mr Abbott said the IR policy was an important element in the Coalition's plan to create a million new jobs in five years, and two million new jobs within a decade.
He pledged to restore right of entry laws "that Prime Minister Julia Gillard promised back in 2007".
The importance of productivity in enterprising bargaining would be re-emphasised under the Fair Work Act, he said.
The Fair Work Act will be changed to ensure that if protected industrial action is to occur, the parties involved have been "talking first and striking later".
"Importantly we want all workers to have access to individual flexibility arrangements, and we won't allow them to be excluded by enterprise bargaining agreements," Mr Abbott said.
"But the heart of our policy is ensuring that the rule of law operates in our workplace and that unions and other industrial organisations are run honestly and in the interest of our members."
Mr Abbott said workers had nothing to fear from his policy. "I want to assure all the workers of Australia - unionised and non-unionised - that they can trust their future in our hands," he said.
Mr Abbott said he believed he had been a successful workplace relations minister in the Howard government.
He was one of the few cabinet ministers who argued against the controversial Work Choices reforms.
He also pointed out he had been a member of a union when he worked as a journalist in the 1980s.
"I understand unions, I respect well-run unions. I understand and respect unionists. But I also understand and respect the 87 per cent of workers in this country who choose not to be members of unions," he said.
"We need a workplace relations system for everyone and that's what the coalition intends to deliver under this policy."
Mr Abbott said the changes were "fair-minded", but he expected a strong response from unions.
"There is absolutely no doubt that unions will shout the house down over this," Mr Abbott said.
"But I don't think any fair-minded reader of our policy would see anything other than sensible fair-minded changes.
"Who is against improved productivity? Who is against improved flexibility, provided it passes the better off overall test?
"Who is against more honestly run registered organisations?"
