A co-worker, Bob, and I have been working on a project that was supposed to be completed together. Due to his lack of time management, he has been stuck on a bug for over a month. Today, Bob merged some code into our master branch.
The issue is, the code that Bob merged into the master branch was code I had written (line for line).
I am unsure how to move forward from here. I can prove that I wrote the code first, but does that even matter?
How would one go about addressing this issue with a passive manager?
