Legislation aimed at removing barriers to fathers working more flexible hours so they can look after their children is expected to be debated in Federal Parliament this week.

The Federal Government says while workplace participation has increased for women, mothers still undertake a much greater share of unpaid responsibilities.

Minister for the Status of Women Kate Ellis says the move to amend workplace equality legislation will be a win-win for both parents.

"We know that there are many men who want to pay a larger role in bringing up their children and they require more flexible working arrangements to make that reality," she said.

"Recently we've introduced changes to the Sex Discrimination Act. And importantly this means for the first time women and men will be formally protected in the workplace from discrimination based on their family and caring responsibilities."
