Steve* and I started working in a new team at the same time from different areas in the company. We do very different roles that complement each other.
We started off quite friendly, we were in touch before our interviews, during the process, and then waiting to hear if we got the job. Then we were both excited to start. I thought we got on quite well and had a laugh.
The team generally WFH or goes into 2 separate offices based on our nearest location. Me, Steve and another guy are closest to office 1 so we began to arrange days to work in the office and had a couple of occasions of after work drinks.
Steve started to cool towards me after 2-3 months and he became friendlier with the other guy in our team who did the same role as him.
Then he stopped really conversing with me on Teams and ignoring me on work calls/in the team chat. When I say ignoring I mean if we both joined the meeting first he wouldn't even say hello or acknowledge me.
When I've asked for support with something he says it's not in his remit or he doesn't have time and continuously makes out his job and time is more important than mine. He refuses to collaborate.
We all worked at office 2 one day and he offered me a lift there however due to the distance I stayed in a hotel the night before so asked for a lift to his nearest train station on the way back home cutting over an hour from my travel time. He agreed so I hung around an hour after I'd finished waiting for him, for him to say he didn't know when he'd be finished and I'd best just go. So I left and got a cab only to see him and the other guy leave just after me while I was waiting. It was pouring with rain and I had to get 3 trains with 1 connection a 20 minute walk and obviously I got home and hour later than I would have done and 2 hours after he would have done.
When we have a team day in office 1 we all book seats next to each other as the whole point is to work together. I scheduled an in-office day and said to Steve and the other guy where I was sitting. They ended up booking seats on the other side of the office so I was sitting on my own. I said to Steve I thought it was out of order and whats the point of coming in as a team to sit away from each other, he said we were in the office together and he didn't think that meant we had to be sitting on top of each other.
There's constant snide or patronising comments from him and undermining me in meetings.
As we mainly WFH I can mostly ignore him but it's given me a complex as to what his issue with me is and there will come a time very soon when we will need to work closely on a project together and I don't know how to handle this.
Does anyone have any advice?
