Good news! My team manager wrote the content, and when we met 1:1 yesterday for our weekly meeting, it did not even come up in conversation as an issue or point of contention for him.

I even initiated on my own doing research to identify sources to help him with the next content piece he is meant to write, and he was very appreciative of my efforts to help.

So, I managed to sidestep and navigate my way through this work issue without getting into trouble and without causing open conflict and tension. I am very happy about the outcome! YAY!
