About a year ago, my team leader decided that she would start delegating tasks for me and a colleague to tackle as a pair. It started out just fine, it was our first pairing job, and we were trying to adapt, and we kind of got the hang of things, and started getting the benefits of pairing for like a week. But thing is, maybe we're not too compatible, maybe we don't think the same way, but when we disagree about two viable solutions it often feels like discussing the disagreement is unproductive and we get hung up on small stuff with no mutual decision, and given enough discussing it gets exhausting.
Anyway, as the months dragged on, constantly having to sit together and work side by side got tiresome, so we fell into the habit of each working on different parts of the task, or one working while the other didn't really participate too much. We're on very similar skill levels so eventually it got to us just discussing what should be done and then one does it while the other waits, only getting involved if something unexpected comes up. We kind of burned out of each other, or at least that's what it felt like to me. I tried raising these concerns with my superiors and they reacted by asking for specific reasons why we're tired and I couldn't really explain so they basically insinuated we just weren't doing it right, and just "give it time" and we'll get the hang of things.
It's been almost a year now. I took a vacation and upon returning we got back to pairing and we had a really productive first few weeks, it felt like all I needed was a break, but now we're distant again and not really working together, even though we're technically pairing.
I'd like to know, is this a common thing? Is the company doing something wrong or are we not pairing right? How common is it for the same pair to work together for a full year? What should be done about this?
