This colleague specializes in an area all of us are supposed to cover as well. Naturally, we cover less than him as we have our own things to do too.
They try to dominate and act as a pseudo manager, the manager is bad at coordinating people. Everytime I ask a question, they refer me to the supid written documentation. For the life of me, I have read those. Those are just shortly explained policies which do not explain the technical questions or a lot of nuances and gray areas. I hate their attitude. This results negatively in my job.
Any advice?
