So one of our sub teams had issues with me splitting a single function in two to help implement a feature that should be in their component in the first place.

All I did was suggest it as a possible solution and got a nasty email in response with my boss left off of the recipients list but my bosses boss listed instead.

Apparently we needed a meeting to suggest the idea of suggesting a new idea and three to four weeks to decide if we should implement it.

This sub team constantly complains that we don't approach them but at the same time makes themselves the most unapproachable group of people on the project.
