Back in June I completed a task and asked a project manager to notify the client it was completed in a public work chat. That project manager stated it is not their project but will talk to who they believe is the project manager since he was having a meeting at 3pm with him.
At this point I basically forgot about it and moved on; but nothing was ever done.
Fast forward to September, the client is asking me directly who was notified that the work was completed? I found myself with my pants down and I go on our work chatroom and ask about how to respond (as I don't communicate with clients normally) and I made a note in the chatroom (which the big boss can read) about how I asked the project manager to notify the client and that I am not sure what happened.
I feel like I am basically blaming others and that it wasn't my job to notify the client and that I handed it off to him and he told me he would see it through. How could I handle this better besides assigning blame? I obviously don't feel like I am at fault but I don't want to point fingers either.
