McDonald's will investigate allegations that a former employee in Ireland faced taunts at work after she was raped by a colleague at a house party 10 years ago.
Ciara Mangan, 28, from County Mayo, waived her right to anonymity this week and spoke publicly for the first time.
Shane Noonan, 28, of Castlehill Park, Turlough Road in Castlebar pleaded guilty to the attack and was sentenced on Monday.
Ms Mangan said her colleagues subjected her to "rape songs" and "rape comments" in the aftermath.
It comes as more than 100 claims of sexual assault, harassment, racism and bullying at McDonald's emerged in a BBC investigation earlier this week.
In a statement, the fast-food company's UK and Ireland chief executive Alistair Macrow said: "I commend Ciara's bravery in speaking about her horrific experience.
"I am deeply appalled by these new allegations and commit to investigating them to our fullest extent through our investigation-handling unit."
'Source of entertainment'
Noonan was jailed for seven years for what the judge described as a "cold, predatory and premeditated" rape of Ms Mangan.
Irish broadcaster RTÃ reported, external that she told the court the attack happened in May 2013 when she went to a party with work colleagues and became unwell after being handed an open can of cider.
She said Noonan guided her upstairs and then raped her in the bathroom as she drifted in an out of consciousness.
Following the attack, Ms Mangan told the court she was taunted by work colleagues who "found it funny and a source of entertainment".
This, she said, was "absolute hell on earth" and made her doubt herself.
"I felt confused, embarrassed, disregarded, bullied, stressed, overwhelmed and that I wouldn't be believed," she said.
In an interview with The Irish Times on Friday, Ms Mangan spoke of some of the alleged workplace harassment., external
"Everybody in work knew I was raped and it was the joke of the day. Then the tormenting started, and for the next 10 months," she said.

'Fallen short'
On Friday, Alistair Macrow issued an "unreserved apology", external to those affected by allegations made public through a BBC investigation this week.
Announcing the establishment of an investigations unit, Mr Macrow admitted the business has "fallen short in some critical areas".

He said the chain is also appointing external experts to independently examine how workers' claims are "escalated".
"I am determined to root out any behaviour or conduct that falls below the high standards of respect, safety and inclusion we demand of everyone at McDonald's," Mr Macrow added.
