Currently having problems with a colleague I’m supposed to be working alongside. TL;DR at the bottom of this post.
On a shared internal initiative we’ve been working on for the last couple of weeks, she started the work without involving me, didn’t ask for my input, and presented the work she’d done to senior managers before I had contributed (we’d been told we were working on this on a Friday afternoon and she had worked on this by herself over the weekend to have the presentation ready for Monday).
More recently, I independently developed an AI/automation costing and capability analysis without knowing she was already involved in an internal initiative working on something similar.
I’d presented this to our head of department who was impressed by the analysis and added me to the group so that we could leverage my work to shape the work stream, but since then she’s repeatedly stressed that they were already working on it where she started by talking to me from across the office floor and in front of colleagues saying ‘we shouldn’t be doubling efforts, we’re already working on this’ even though their work was nowhere near as well developed from looking what they’d done so far.
Aside from responding to my messages in a condescending and patronising way, she also rarely acknowledges or builds on my work and generally seems to prefer working separately. I’ve messaged her privately saying I’d like to discuss this alongside how we can work more collaboratively together and have booked a short meeting for Monday, but she’s read the messages and not replied.
How should I handle the conversation? If she ignores the meeting or refuses to engage, should I raise this with somebody more senior? It gotten to the point where our colleagues have started noticing her behaviour and hasn’t contributed to a positive working environment, particularly for me.
TL;DR colleague is dismissive, condescending, and won’t work collaboratively with me for reasons that are unknown to me. She hasn’t engaged with my efforts to resolve this directly, either. What do I do?
