The Australia Institute's Centre for Future Work has found employers are getting six hours of free work each week per employee.
New research shows the average Australian is now working two months of unpaid overtime a year.
The report has found Australian employees will work a total of about 3.2 billion hours in unpaid overtime this year.
It found unpaid work is highest among the self-employed, at over eight hours a week, followed by full-time workers at seven hours a week.
Part-timers averaged over four hours without compensation, and casuals averaged almost three.
