Don't know what to do with this...

Is the workman attractive? If so, it could well be the bf feeling threatened.

On the other hand if he's nothing to look at then perhaps he was really perving at her and the bf is worried 🤷🏻‍♀️

Either way, I wouldn't say anything. It's only going to cause problems. Maybe just warn the bf when the workmen are going to be back and say they'll be done soon.

Or she could have made it up to make him jealous.

Or OP could be employing someone who enjoys making female children feel uncomfortable.

I really hope someone takes your children's concerns seriously.

It could definitely be that he's a weird perv, as I mentioned. I'm still not sure what's to be gained by saying something. You can't really tell somebody how to look... it's pretty subjective and there's no evidence anyway.

I agree with this, also under new secual harassment laws you could be held liable yourself as the employer.
It takes a lot for a child to speak up, good on him for mentioning that she felt uncomfortable, now its up to you to step up and nip it in the bud.

When my dd was 15 her bf (now ex) was upset because she mentioned that an elderly man had sat beside her on the bus. She has reported many times to me about people looking at her funny, both male and female, so I would completely disregard this tbh. If you are concerned you could speak to the girl herself and see how she feels about you talking to the workman.

Young women who often attract unwanted attention from men? Is that what they are like?

Interesting. I'd be even more inclined to say something then, but with the right tone. Because eitehr there IS somethign odd goign on, or, more likely, these 16 year olds are a bit ridiculous and your builders should know to be a bit careful.

Some of these comments are awful and really ignorant. It is intimidating as a young woman to have men staring at you, this young woman is having it in her own home too. Have you all forgotten what men were like when you were young? Have you all forgot how many women are sexually harassed and sexually assaulted?
I'd talk to the workmen but I would approach it neutrally. Just say "there's a teenager next door who has said she felt uncomfortable with one of the men looking at her, maybe face the other direction when you go out for a smoke to avoid any complaints".

So if he is good looking it must be an issue with the children not the adult?
Do you think attractive men couldn't give out unwanted attention? Isn't that one of the defenses of Russel Brand being trotted out on social media, "women were throwing themselves at him, why would he rape anyone".

Yeah of course it could be that as well. It was just one possibility I'd raised. As others have mentioned, there is the possibility that bf is being controlling or gf was being manipulative. We don't know, do we. All we have to go on is that he looked at her funny, which could be anything. So I don't think it's something you can really have a chat to him about.

Workmen on my street have 1. Left litter 2. Had unnecessary loud voices when on a break outside 3. Had used swear language around neighbourhood kids 4. Smoked all sorts 5. Blocked pavement 6. Ruined common grass areas

It is a problem. Their customer wants the job done as quick and as issue- free as possible. Also he doesn't directly employ the workers and can’t monitor or demand certain behaviour.

I believe the girl was made to feel uncomfortable. She shouldn’t have that so near her home. However, saying something will probably just make the behaviour worse.

You could tell the workmen (better the foreman) the young teenage girl next door felt embarrassed by the men (or one of them) looking at her when he was smoking outside, your DH may be able to phrase it better man to man so to speak, but not making a big thing of it. If the boyfriend comes to see the workmen it could end badly, probably for the boyfriend.

OP believes her workmen have worked so hard they couldn't possibly have time to have leered at a young girl, so....

How old is the boy friend?

'Protecting your women' is the excuse used for all sorts of toxic controlling behaviour. I actually think it is a red flag. If there was an issue the next door daughter should be telling her parents or telling OP herself. It's highly likely he took this on himself as the big protector or a jealous boyfriend. None of these are good and are only the start.
There needs to be a conversation with the next door daughter and her parents to establish exactly how it made her feel and exactly what happened. Not a conversation with a proxy.
And you can't go to the work men based on a conversation with the boyfriend. However you put it, it's an accusation so you need more than a third party vague conversation.

Wow I hope none of you work in places of responsibility with children or vulnerable adults.

Its not your job to investigate but simply listen, believe the child, and report accordingly.

I have a 16 Yr old daughter and am i childminder and am honestly disgusted by some of these responses.

Me too.

@vellichoria I would have a word with their foreman/person in charge and say, it could be nothing, but just to know a neighbour has reported that they were made to feel uncomfortable by one of your workmen staring at her. Could be worth having a chat with them about how they manage themselves around the general public. And let them know they are on CCTV on the drive etc.

And I would be watching them like a fucking hawk from now on.

The petrol station near my home is the one all the work crews use because it is easy to get trucks in and out. The discussions I have heard while fueling have made me genuinely fear being home alone with any kind of work crews. They speak very differently about women than the men I spend my days with at work and in my social life. Some of this is likely bravado. I doubt they are all acting on what they say, but what they say and the attitudes towards women are disturbing.

My first instinct would be to listen to the boyfriend and worry that you have a problem in your home. I’m not sure what you can do about it except keep an eye on the situation. If you have cameras, I would check them.

'It happened to her before' - did the same workman 'look at her funny' or was it some other man/men?

I'd have told the boyfriend to speak to them directly himself or report.

Seeing as your husband has said he will speak to them, I think your beat course of action is to instead speak to the girls parents because tbh there us as much of a chance the boyfriend is a controlling dick.

I'd say "just wanted to catch you and make you aware of a concern raised to us by Xs boyfriend. Given her age, we wanted to make you aware. Should you want to pick it up with the builders, please do come by and speak with them (yourselves)."

Why did the girlfriend not come round herself? Fishy.

What are they like? Better at listening to their intuition when a man looks at them like he wants to fuck them and then chop them up in to little pieces? Yeah, they are good at that. Until the adults in their life just tell them "he's only being nice" or "it's because you are becoming a woman".

I'm not sure how I'd approach it OP. But I'd be very wary of the man she felt uncomfortable with.

The number of men who "looked at me funny" when I was "14-18" who ended up with allegations or convictions for sexual crimes is staggering.
