Having a hard time with a man at work

I'd go for a touch of condescension mixed with sarcasm- "My my, you've got it all figured out haven't you? No wonder you're having such good luck with the ladies!" Tinkly laugh I wouldn't bother trying to change his mind or even get irritated to be honest - he's not worth your time and energy.

@AssangesCat I wouldn't do that tbh. If he already holds these beliefs he's not 100 miles away from trying to hurt or sabotage Op.

no need to be childish

it's a simple reasoning, if you can't handle an immature colleague on your own but need me to hold your hand to do that, how would you manage same employee once YOU are his manager?

today's example given by the OP is 2 people disagreeing with each other. He just turned away and scoffed and I feel annoyed and frustrated. seriously, you would want me to get involved in there? I would because that's my job, but don't expect me to take either of you seriously. It's like being in a classroom and having to tell people to shut up and keep all discussion business-related to avoid any upset. What I'd personally think about the comments is completely irrelevant.

I agree with others, don't engage just a short standard response repeated each time he comments - " really, that's nice" or similar dismissive slightly more polite way of saying "whatever". Also a log is good buy I think he'll get bored pretty quick if you don't engage.
I don't think it's necessarily a cultural thing, my hubby is Polish and I know quite a few eastern Europeans from various countries and they are all different in the same way women are all dif. My hubby cries when something sad happens or when he's very emotional.

I've raised this with my manager who said he hasn't noticed.

"Obviously not, that's why I'm making you aware. You do realise that sexism in the workplace is a form of discrimination, and illegal according to the Sex Discrimination Act of 1975?".

Sounds like he is just an opinionated twat, tbh. I second keeping an obvious diary.

I find a half hearted smile but no verbal response goes a long way to making games like this as boring as possible for the other person.

Some people do tend to think in those kind of sweeping generalisations. I think they can be people who have a hard time understanding social interactions or why people behave in certain ways. So they are inclined to pick up these ideas, sometimes they can be quite weird. But they are the only tools they have to try and make sense of things. They might be poorly educated more generally.

If he is basically a nice guy, I would try and treat him, in those interactions, kind of like he has the brain of a 14 year old boy. So set a good example for behaviour that might make him question his assumptions, or ask questions about his statements from time to time. Not all the time, but when you think it might really make him think. ou could say, "well, I am a women, Mike, and you know I don't do that. Do you think maybe it could be that women have a lot of views on that issue?" When you don't want to engage, ignore it or just say "Oh, I don't think that is true" and carry on.
He might have some sort of mental or social deficit, and a lot of men at 25 are still pretty immature these days. I always think if we can, it's good to help them toward a useful maturity rather than send them into the arms of weirdo conspiracy theorists.

If he does it all the time then bore him with "Have you met every woman/American/English/gay person? No? I didn't think so." End of conversation. Every single time. Until he's so bored with it that he stops bothering to make sweeping statements.

But I definitely think all men should wish us a happy international women’s day!

Is he Russian? I think international women’s day started there didn’t it and is more established iyswim?

Racism and homophobia OK or just sexism lacasta?

if an adult is unable to deal with another adult from the same team then no, I don't give them much hope of progression.

It's not bullying. If you think that's what bullying is, you prove my point. Don't worry, the "mean" guy will be punished accordingly. But the one who needs the boss to hold her hand won't go very far.

I bwt the last time Jeff was anywhere near a vagina was when his mother gave birth to him.

I'd probably just say "how would you know?" To any comments about what women are like as he clearly has no experience to comment.

Don't expect to go very far in the company if you need to tell the boss when someone is being mean to you.

That won't be what's happening, should she take details of the issue to HR/her manager. To continually have to field sexist statements at work is not acceptable. Just as having to continually field racist or homophobic statements would be. This is not about someone being "mean". And actually, even if it were, continually bullying at work is also not ok, and companies should be looking to stamp it out.

To ensure that someone who reports sexist harassment to you doesn't go far within your company is harassment in itself.

I'm sorely tempted with this one
And plaster his desk with these.

Ask him why he is mansplaining what women think, to a woman.

to be honest, if someone comes to see me at work to complain about that kind of comments, I would of course deal with it. I would also be very unimpressed with the one who complains, I am not a teacher dealing with school playground squabble. Don't expect to go very far in the company if you need to tell the boss when someone is being mean to you.

Some of the posts on here are genius and I wish I had the guts to use them.
I think I would probably just smile wearily and say 'ok if you say so' and turn back to work.

You should definitely grey rock him as in pelt him with one

I’d get a diary and write every single comment down...then I’d present it to my manager ..but I completely ignore him while doing so

You don't need to put in those terms to the chap himself - who may well be an idiot, as much as a troll. Deflection is good.

But your manager needs to know what's going on and that it's interfering with your wellbeing and taking up your time.
