How would you feel if someone did this to you?

[Saveone]

I've just started a new job and mostly everyone seems friendly. There's one person in particular who seems really cold towards me. Earlier today I saw them and they were having a laugh with another colleague. They were still smiling about it when they walked towards me, then as soon as they saw me they stopped smiling and looked away from me.
As I'm new I'm making an effort to smile and be friendly but what happened has left me feeling pretty rubbish.

How would it make you feel?

Well, it's obviously weird behaviour.

It would upset me.

But really it says a lot about that person. Not about you. They weird. They don't even know you and they can't even manage the basic social niceties.

Lame.

So do not be a try hard. Just be formal, polite and do not try to engage them.

You will settle in, make good networks. Try not to let this one twit get to you.

Ignore them. Not everyone will like you and you won't like everybody.

It could well have been they were in the middle of making some bitchy joke about the boss or something, saw the new person and thought 'argg..better shut up. But I CBA to make friends with them now so I'll just move away'
It's nothing personal against you. They may well be a dick. Or they could turn out to be alright. Just don't worry about them and you'll soon see what they're like.

As long as most people are ok I would not give the idiot any head space. If I was working just with them it would probably bother me

Don't worry about it, or give it a second thought.

I moved divisions in the company 18 months ago and saw my old line manager in the office a while ago and said hello, he completely blanked me, wouldn't respond. Told the silly bugger to grow up. Stupid behaviour from some who is a director as well.

I'll still be polite if I see him again, as manners cost nothing.

If they want to act like kids, let them.

Weird behaviour..

Is there any reason why they could be acting like this?

Have you spoken to them at all since you started?

Probably see you as a threat.
That you might be better than them in the job or become part of the social circle that this person is already happy with.

I would think ‘wow she hasn’t grown up’.

Ive encountered people like this. They usually want a rise from you. They want to see ANY reaction from you, so don’t feed it. Be neutral, act like you haven’t noticed. Don’t internalise it either, it says everything about her and doesn’t reflect on you at all. She’s shown you who she is, so just avoid her. There’s always one idiot, sounds like you’ve found her.

It wouldn't bother me, I'm long enough in the tooth and well enough able to stick up for myself not to care about random co workers. If someone wants to ignore my hello or acknowledgement it's no skin off my nose

They definitely don't see me as a threat. I have no idea why they acted this way.
Next time I see them I don't know whether to smile or not. I don't want to look like I desperately want them to like me, but don't want to come across rude either.

Just give them a polite 'Good morning' or whatever if appropriate but don't try and start a conversation unless it's work related.

School-girl bullying tactics, trying to see how you act and if you get mad or upset, or the prize ...cry. Don't give them the satisfaction, be your usual nice self to the other workers and (try) to ignore the shit disturbers.

There are absolutely loads of reasons she could have done it. She might have done it deliberately to make you feel bad. Or she might have been joking and then suddenly remembered her dead cat and her face fell. Or 100 other reasons - I would say based on this alone don't internalise it as definitely being about you because you were in her eyeline. It might have been, but peoples faces do weird things for no reason sometimes. So, don't let it get to you - its usually better to give people the benefit of the doubt and if it turns out she was doing it on purpose then that will annoy her so its win win.

They might be taking their resentment out on you because you got the job they wanted. Maybe they applied for it and got turned down. Maybe there has been some internal reorganisation in the department now you've arrived and they feel hard done by.

I know at one place I worked, there was someone who took a real dislike to me and months later I discovered that I'd been given their desk and they'd been told to sit at another one!

On the upside, it is good they have revealed themselves early so you know what they are like. As someone said above, formal and polite. Hopefully, everyone else there will be lovely.

Hard to know.

Maybe they applied for your job and didn't get it.

Maybe they are shy and struggle to make eye contact with strangers.

Maybe they're just mean.

A breezy "Morning Ladies" then just walk by.

Absolutely pathetic behaviour. I’d sarcastically ask them if they are ok if they do this again but equally ignoring them isn’t the worst idea either.
