ChatGPT is good for this kind of thing.
"1. Frame it with clarity and professionalism:
I’d like to raise concerns about a pattern of inappropriate comments made by [colleague’s name] that I believe create a hostile and unprofessional work environment, particularly for women.
- Address each type of comment and explain why it’s a problem
Sexist or undermining maternity leave
He has made comments implying that women who return from maternity leave are less capable or out of touch. For example, when I asked a question after returning, he said, ‘This is why women shouldn’t come back from maternity leave.’ This comment was not only unprofessional, it was sexist, and it undermined my credibility in front of colleagues. It reinforces outdated stereotypes about working mothers and creates a culture of exclusion.
'Training your wife' remarks
He’s also made remarks along the lines of ‘training your wife’ which are deeply misogynistic and objectify women. These kinds of jokes normalize power imbalances and disrespect in relationships, and they don’t belong in a professional environment.”
'Prostitute of the IT world'
In a recent meeting where I was the only woman present, he referred to himself as ‘a prostitute of the IT world’ in reference to being a consultant. This not only brought inappropriate sexual language into the workplace, it made me feel extremely uncomfortable. As the only woman in the room, I was left feeling isolated, as though I was expected to tolerate language that wouldn’t be acceptable in any professional setting.
- Emphasize the broader impact:
Taken together, these comments create an environment where it feels harder to be taken seriously as a woman, and where sexist attitudes are allowed to go unchecked. It affects my confidence in contributing in meetings, and it sends a message that this kind of behaviour is tolerated.”
I'd personally take out the bits about affecting confidence but the broad framework and comments seem sound.
