tl;dr; A co-worker and I had an disagreement on our package structure. They went straight to our team lead instead of trying to solve this in our team and by that letting me do my job.

Do I overreact by assuming that this was malicious?

A co-worker asked me to do their code review today. There was nothing really wrong there, mainly something a bad generator created.

However at one point we had a disagreement about the naming structure of the packages. We both agreed to disagree, so I thought we could bring that up in the next daily, as it's something the team should agree on.

Shortly after that, they told me on Slack, that they relayed the matter to our team lead to get their opinion. Wtf.

My role in the team is that of a technical lead. Even though I like to discuss such topics in the team and not straight up dictate decisions.

By going directly to our team leader, they basically circumvented the whole team. This really rubs me wrong the way.

Maybe I'm just overreacting?
