Australian employers are getting away with breaching their legal obligations to pregnant women and parents "scot free", according to Victoria's Legal Aid.

The state's legal aid service released a short YouTube clip in response to a report handed down by the Australian Human Rights Commission (AHRC) last week, which found widespread discrimination against expectant mothers.

The video was launched today at the Victorian Equal Opportunity and Human Rights Commission, with Australian Sex Discrimination Commissioner Elizabeth Broderick.

Legal Aid said employers who breached their legal obligations were not being sanctioned.

"The report that recently came out from the Australian Human Rights Commission has shown that by and large, women don't make complaints when they experience pregnancy discrimination," said Melanie Schlieger, the manager of Victoria Legal Aid's equality law program.

"Ninety-one per cent of women make no formal complaint of any kind.

"It's a really significant issue and it means that employers who breach their legal obligations get away scot free."

The video features women telling their personal stories of workplace pregnancy and parental discrimination.

The AHRC report found 110,000 women experience discrimination each year and just one in 10 seek advice.

Ms Schlieger said that just knowing what their legal rights are could reduce the incidence of discrimination.

"There are a whole range of reasons why women might not want to make a complaint, first of all legal proceedings are the last thing that a pregnant woman or a mum with a new baby feels like doing," she said.

"That's very understandable, they're time poor, they have other priorities in their life.

"They might also be concerned about their reputation.

"What we want women to know is that they don't necessarily have to go to court to get a better outcome, there are other ways that they can achieve this and simply by knowing their rights they can improve their situation."

She said women had a range of legal rights under the fair work act and discrimination legislation and they could contact their union, legal aid or community legal aid centres if they face discrimination.

"I'd also really encourage women to have the conversation with their employer in the first instance," she said.
