In the meeting I sign off on the team's work and tell them it's good to go. Then I go home and quietly redo parts of it at night, changing what I already approved. They think it's finished; they have no idea I'm reworking it behind their backs.
More people experience this than they realize.
You approve work publicly, then secretly redo it after everyone's gone.
If this sounds familiar, the Library can help you find the bigger picture.
