More than four million people have experienced sexual harassment at work in the past five years, with incidents higher in male-dominated sectors like construction, retail and mining, violence prevention organisation Our Watch said.

More than 40 per cent of women experienced sexual harassment at work compared to just over a quarter of men.

The perpetrator is a man in almost 80 per cent of cases.

Bosses will be supported to meet new regulations that require businesses to actively take steps to stamp out sexual harassment at work under the Lead the Change campaign launched on Monday.

Workplace sexual harassment was too prevalent and occurred because of sexism and disrespect, Our Watch CEO Patty Kinnersly said.

“By creating a culture of respect and equality, workplaces can prevent sexual harassment,” she said.

A more gender-equal workplace provided benefits such as fewer sexual harassment reports, Ms Kinnersly said.

“This is because these employers are more likely to have more policies that support gender equality in the workplace,” she said.

Thousands of women had been pushed out of the workforce and away from job opportunities because of the way they were treated, Prevention of Family Violence assistant minister Justine Elliot said.

“Too many women in Australia are denied the basic right of working in an environment that is free from harassment, disrespect and bullying,” she said.

“We are looking to industry and business leaders to take up this challenge and help us stamp out this unfair treatment.”

The survey commissioned by Our Watch included 200 business leaders working in organisations with more than 10 employees.
