Is Labour Market Deregulation Good For Australian Workers?
Yes. No-one can guarantee your current job. The only real guarantee is the capacity to quickly get a new job if needed.
The only way to deliver that to all is through an open and flexible labour market that allows workers to negotiate (either together or collectively) their own terms and conditions.
A labour market bogged down in complex rules and regulations discourages employment and locks people out of jobs---which is why the duration of unemployment is climbing in the highly regulated Australian labour market and falling in the open US labour market.
