Just need another pair of eyes on this as not sure what to do.
I started a new role about 6 months ago at a small org, I really like my job, and initially got on really well with my team and the wider team.
However, recently things have taken a strange turn. There is one person in particular who seems to have an issue with me, so for example a minor thing I did to annoy this person has been blown up. The issue is that once this person is annoyed with me, the whole team is, including my line manager. I've literally directed friendly questions the three of them and been ignored, they refuse to make eye contact etc. Lots of small things like that and it sounds pathetic but it's making me really unhappy and stressed. The way we are set up is that I spend 80% of my day just with my direct team.
There is a suspected relationship between the line manager and my colleague, and another minor team member is particularly close to this colleague too. The colleague is also older than me, in a lower position, and has been there longer. I think this is the crux of the issue with me. Anytime I have been given a bit of extra responsibility or credit the treatment I get seems to get worse. I also think they think I told my line managers boss about something he did wrong. I did tell the boss what had happened after being directly asked, as they needed to know prior to the repercussions and they were definitely going to find out from external sources, frankly what he did was so ridiculous and unprofessional it'd be a cheek to blame me. I have another colleague who is lovely and not part of any of this.
My line manager also undermines or criticises me in front of this colleague, and they all travel in together and have lunch together somewhere separate. It's making me very paranoid that they bitch about me.
What I can't work out is, is this bullying or is this just them not liking me? Obviously this is a workplace not a friendship so I don't know where the line is really. Nothing horrible has been directly done or said to me, but it's making it very hard to do my job and making me want to leave.
When I first started there was another member of staff who was very isolated and quit soon after a row with the same person. I wish I had got to know him better to find out what happened there but can't contact him now.
