A Google boss told clients he was a swinger and shared an explicit picture of his wife - leading to a whistleblower losing her job, a tribunal has been told.
Victoria Woodall raised the alert over behaviour by senior staff at the tech giant with its UK HQ in Kings Cross, London - with one manager ultimately punished for sexual harassment.
She says she was made redundant after flagging concerns about a 'boys' club' culture, before facing a 'relentless campaign of retaliation'.
An internal probe by Google UK deemed the manager touched two female colleagues without consent, amounting to sexual harassment, it has been reported.
But Google denies retaliating against the claimant, suggesting she turned 'paranoid' about whistleblowing while she branded 'normal' business activity as 'sinister'.
She told of a 'relentless campaign of retaliation', with friends of the senior manager also later subject to disciplinary action for failing to challenge his behaviour.
An employment tribunal heard that Google funded a men's-only 'chairman's lunch' up until December 2022, amid allegations of a 'boys' club' culture.
The firm has denied such an atmosphere existed, while saying the 'chairman's lunch' events were cut off as no longer in line with Google policies.
Victoria Woodall raised the alert over behaviour by senior staff at Google.
Judges at the London Central Employment Tribunal are expected to rule in the coming months.
Ms Woodall, employed by Google's sales and agencies team as a senior industry head, told of being contacted by a female client in August 2022 raising concerns.
The client said that one of the team's managers bragged during a business lunch about how many black women with whom he had had sex, the tribunal heard.
The Google chief is also said to have described how 'he and his wife were swingers', the court was told based on summary notes from Google's investigation.
The client herself branded the alleged behaviour 'disgusting', saying the Google boss's line manager did nothing to stop him.
Ms Woodall then reported the worries to her chief Matt Bush, then the agency team's managing director of the agency team, prompting the Google internal probe.
She then issued a second complaint from another female client accusing the same official of showing her a photo 'of his wife's vagina' on his phone, the claim says.
Google, which interviewed 12 people in its inquiry, is said to have found the manager did sexually harass two female employees during a work event.
He was accused of touched one colleague's leg while talking and rubbing another female colleague's back and shoulders - each time without consent.
The man was also ruled to have made inappropriate remarks to workers, such as telling one he was in an open marriage - adding that should she have sex with him', his wife would 'enjoy hearing about it'.
The manager denied the allegations during Google's inquiry, saying he did not think he told colleagues of having an open relationship.
Tribunal documents show he was ultimately sacked for gross misconduct while his line manager and another senior workmate were order to undertake 'documented coaching' after failing to intervene, the BBC reported.
They were later made redundant - as was Ms Woodall, as part of a process started by Google in 2023 and which ultimately led to 26 people being let go from her team.
Ms Woodall raised her concerns about the alleged 'boys' club culture' at the firm in May that year.
She told of being given 'little choice' but to exchange her successful client account for a failing alternative, which she described a 'poisoned chalice'.
Ms Woodall told the court she was subsequently demoted to a subordinate position on a large internal project - in support of the senior manager she had reported.
She was made redundant in March 2024, as was a second senior manager embroiled in the earlier misconduct probe.
Ms Woodall remains a Google employee, receiving long-term sickness payments for work-related stress, according to her employment tribunal claim.
Google has denied she was made redundant for whistleblowing, saying 26 members of her team were affected by the wider department closing.
The BBC said the firm accepts her report about the manager facing misconduct allegations amounted to whistleblowing but rejects claims of retaliation against her.
Google UK has described the tribunal claim as being 'without merit'.
The company also insisted there were 'strict policies around employee conduct while complaints were taken 'extremely seriously', adding: 'Where our internal investigations show violations of policies, we take appropriate action.'
