I have been working on a project. Sometimes, the requirements will simply change, or some previous decision would be inadvertently "overturned".
As an example; suppose we are making a site. We decide that we will not add any animations until we complete x, y, and z. The next week, before we finish y and z, I see animations on every page. I ask the team "why is there animations if we haven't finished these things?". Surprisingly, they reply they have been working on animations for a while now and have finalized everything.
I feel baffled because I have never even heard them mention this once. Clearly, it sounds like the rest of the team was informed, it is only me who wasn't. I check my calendar, my messages, my email, any place where this could be mentioned, but come up empty. I was certainly not invited to these meetings, nor did I even know they happen. I didn't even receive any sort of summary/update of what they were about.
I started to get a little suspicious, and noticed that one teammate was having meetings with the other two teammates on a regular basis, but I was not invited nor informed. I asked him why, and he seemed pretty evasive in answering. I felt uncomfortable pushing the question, because I had an underlying feeling there was something I didn't know that was going on.
Honestly, I am perplexed as to what to even make of this. I almost feel like these meetings are kept secret from me, given that I had no clue they were ever happening and the results of them were never shared with me.
What's the best way to handle this situation?
