The Nine Network has assured staff that, while it can't rewrite history, it's committed to a respectful and inclusive culture following damning accusations of bullying and sexual harassment levelled at its former ratings giant Don Burke.
Nine chief executive Hugh Marks wrote to staff on Wednesday telling them "we all accept our role in ensuring we have and maintain a culture that has zero tolerance of inappropriate workplace behaviour."
"Everyone is entitled to come to work at Nine confident that our workplace is safe and that inappropriate behaviour will be dealt with effectively," he wrote.
Mr Marks said current and former staff have access to counselling to report inappropriate behaviour.
"As much as we might like to, sometimes we unfortunately cannot rewrite history," he wrote.
"But we can and will take steps to ensure that former employees, perhaps with old grievances, are supported."
His letter comes on the day the Senate called on media bosses to show what they've done to stamp out any "insidious culture" which may have enabled sexual harassment.
The Greens motion, which passed the upper house on Wednesday, follows allegations the former Burke's Backyard host sexually harassed and indecently assaulted at least three women who worked on his top-rating TV gardening program in the 1980s and 1990s.
Communications Minister Mitch Fifield said he will raise the issue with media executives.
"I will be discussing with them, and emphasising the importance of having appropriate workplace policies and that there are appropriate responses when these matters are raised," Senator Fifield said.
He said a number of media organisations had told him in recent days they took sexual misconduct "extremely seriously".
