I work in tech in a niche field (think Internet of Things)
I have just started a new job with a massive company. Very excited as more scope to work within this field and more opportunity etc.
I was introduced to my new project (exciting) and told that I would be co-delivering with this person (I'll call her X). I was also excited because there are hardly any women working in this field so it was really unusual to have two working on the same project.
She was less than excited. I haven't had a great welcome. Everything was brisk and authoritative. I was spoken to and given instructions akin to the instructions you would give an administrator. I was then told she would be unavailable for a week as she had a 'big presentation to do' .
A week later my manager asked me 'why aren't you at the expo with X?' . It turns out I should have been at a big industry expo in London demoing the tech and mixing with early adoptors. While I have only been with the company a short while I am an expert in my field so it can't have been that I was too new. And anyway my manager thought I should have been there.
So I checked the company website and expo 'TV feed' and there she was on the panel (that I should have been on) answering questions and liasing with potential clients with her Twitter username underneath on screen. (this is relevant) Her username was something along the lines of @Lady_nichefield .
Anyway I was a little annoyed but moved on. The week after I had lots more 'instructions' but when I tried to ask questions about the project I got no answers. So my tactic to mitigate this was to introduce myself to the wider team and familiarise myself with our project if she wasnt going to help.
I then got emails from her saying 'why are you taking the developers time, you can ask me' I explained that I had asked her and she hadn't answered. I also explained that I had asked the developer if he had time to run over the project with me.
I asked her about the expo and she said 'oh I didnt think you'd be interested'.
She then began inviting me to meetings (with clients or internal team) with either 5 minutes to spare or actually after the meeting had started. Given I'm not looking at my inbox constantly I wasn't seeing them in time which meant I missed a couple and attended one late. Very embarrassing.
I contacted her about this and sent screenshots of the invitations (what time they arrived) and she replied underlining the sentence 'I sent them before' .
So at this point I'm feeling quite unwelcome, a bit in the dark and like I'm running around trying to get to meetings I'm not aware of so I contact my manager to clarify our roles on the project. He tells me I have equal responsibility to deliver but "well she is @lady_nichefield on Twitter so maybe shes worried that shes not the only one anymore chuckles"
So I'm thinking that now this is all a big pissing contest and she thinks I'm encroaching on her 'territory' and that my new manager thinks its quite funny that this might be happening. Its not funny, I've only been there a short while and I feel that shes trying to make me look incompetent.
What can I do?
