Am I overreacting re unwanted attention at work?

[Kaltenzahn]

I'm having slight problems at work and I'm not sure if I'm making this into something it isn't. I've been in a new job for about 2 months now. It's a very different environment to my previous jobs - I'm used to working in small teams whereas I'm now working with around 200 people (around 90% men).
From the very start I've had a lot of attention from male colleagues. This isn't a stealth boast - I consider myself relatively average looking and keep to myself, this is just due to it being a hugely male dominated workplace.
Until recently it's just been people trying to flirt at work (I always minimise conversation and focus on my work so most of them get the picture) which hasn't been a big deal but in the last week or two I've had a couple of people becoming more persistent. Several people have also added me on Facebook (which is fine, these weren't the same people who had been bothering me at work so I thought it was harmless) but a few of them have started messaging me in a way that makes me uncomfortable - messaging me late at night, commenting on my photos, complimenting my looks, asking why I don't have a boyfriend etc. I've even had someone asking me round multiple times to "chill and get to know each other" late at night. The thing that makes me most uncomfortable is that the worst ones are in their 40s and 50s while I'm in my mid 20s - somehow I'd find it a lot easier to deal with if we were similar ages!
I don't do anything to encourage any of this. I try to shut the messages down as politely as possible but some of them are very persistant and I just want it to stop. I'm wary of offending people as they have all worked there a lot longer than me and developed tight knit social groups (which I don't have) and as I'm still in my probation period I don't want to cause any trouble.
This all seems very minor now I've written it down but it's making me uncomfortable about going back into work on Monday. Am I overreacting? Should I just woman up and ignore it? Can I stop this without alienating myself or rocking the boat too much?

I can’t believe some of the advice you’re getting here. (Messolini9!) HR departments are very concerned about this sort of thing as it exposes their organisation to sexual harassment claims.

I would suggest you keep a diary of any / all comments. It’s easy enough to do, open an email, keep it in drafts and add each incident quickly when anything happens. Send it to your personal account every now and then.

You’re in your probation period so you must be having regular meetings with your line manager. Mention in those meetings that some of the comments/attention you are getting is making you uncomfortable. You’re managing it but you want to flag it up.

Definitely remove those guys from Social Media.

It might calm down after you’ve been there a while and the novelty wears off, it might not. It’s making you uncomfortable so documenting it is the first step.

I had this at work 20 years ago, sad that nothing has changed. It was always dressed as funny banter, until one of the more persistent guys cornered me in a lift. You should take this stuff seriously, it’s not something thar should be dismissed, especially by other women.

Message them all a group invitation to watch Bombshell at the cinema with you ..that should put a stop to it

How are you doing OP?

In large groups of men, whether social or at work, they have competitions on who they can pull. New person, particularly if they are young, are targeted and then they move on to the next one. If they pull, kudos points go to the men. All very odd and childish.

Middle aged men are the worse, slobbering over young women.

You owe them nothing. Block them all and be distant.
