Chat about football or cricket in the workplace should be curtailed, a management body has warned.
Chartered Management Institute head Ann Francke said sports banter can exclude women and lead to laddish behaviour such as chat about sexual conquests.
"A lot of women, in particular, feel left out," she told the BBC's Today programme.
"They don't follow those sports and they don't like either being forced to talk about them or not being included."
"I have nothing against sports enthusiasts or cricket fans - that's great," she said.
"But the issue is many people aren't cricket fans," she added, arguing bosses should crack down on sports banter.
Ms Francke is concerned that discussing football and, for example, the merits of video assistant refereeing (VAR) can disproportionately exclude women and divide offices.
"It's a gateway to more laddish behaviour and - if it just goes unchecked - it's a signal of a more laddish culture," she said
"It's very easy for it to escalate from VAR talk and chat to slapping each other on the back and talking about their conquests at the weekend."
Nevertheless, Ms Francke does not think sports chatter should be banned, just moderated.
She said that good managers should be inclusive and ensure that everyone in their team feels comfortable.
But sports journalist Jacqui Oatley thinks cracking down on sports chatter would be a "terrible idea".
"If you ban football chat or banter of any description, then all you're going to do is alienate the people who actually want to communicate with each other," she told the Today programme.
"It would be so, so negative to tell people not to talk about sport because girls don't like it or women don't like it, that's far more divisive."
She said the secret was to discuss sport in an inclusive way and to notice if people were blankly "staring into space" during the conversation.
A majority of people responding to a LinkedIn post from the BBC and on Twitter appear to agree with Ms Oatley.
Former sports, gambling, charities and loneliness minister Tracey Crouch called the Chartered Management Institute's advice "a load of nonsense".
And others agreed with her on Twitter.
I find her comments more offensive. I'm female and a huge football fan. Who is she to say that women don't follow sport and can't be involved in conversations. I have plenty of banter in the office. Just another example of trying to cause drama where there is no need for it. 🙄— Allyson Graham (@AllysonGraham20) January 27, 2020
As a female football (and cricket) fan who engages in a lot of office football banter I find HER comments extremely sexist in suggesting women don’t want to hear about football.— Em Jannie Wood (@EmJanie) January 27, 2020
Office manager Debra Smyth worries that other topics such as Love Island, EastEnders and Game of Thrones could also be censored if sport chatter is banned.
"I personally think companies should not dictate what people talk about, as not talking about it will alienate those with similar interests," she said.
"Where would it end? Banning people with children talking about them so as not to alienate people without children. Certainly not!"
Recruiter Peter Ferguson said: "I have seen managers and staff build a more direct bond over a shared love of sport which has excluded those who don't share that interest.
"The answer is not to ban the conversation, it is to ensure managers and staff are trained to understand that those shared interests should not get in the way of management decisions or working collaboratively."
