Currently, employers and unions that have entered into negotiations have a duty to reach agreement unless there are genuine reasons not to. Removing this would be business-friendly, but open to abuse if businesses wanted to stall negotiations, or floor them completely.
National would also review the rules around constructive dismissal and allow employers to dock the pay of staff who undertook partial strikes.
But National was given a rebuke by a survey of 1300 small-to-large businesses last week, where only about a third believed the Government had a sound economic plan.
Labour wants to raise the minimum wage to $15 an hour and introduce industry-wide standards and a new Workplace Commission to set these standards if employers and unions can't agree.
Labour's policies would push up the bills for businesses - who should focus more on innovation to drive productivity.
The Greens are unlikely to push workplace policies - preferring to concentrate on Green jobs, clean rivers and child poverty - but Act could make youth rates the subject of post-election talks.
Act believes that abolishing youth rates in 2008 priced young people out of the labour market.
