If it wasn't documented, it didn't happen! For years I carried around a small notepad in my shirt pocket. If something happened or somebody said something I jotted it down right then, who said what, when and why. Later it was transferred to my daily log or reports, but I never threw away that notepad. When full, I would throw it in a drawer or box and later to an envelope. You would be surprised how many times that note pulled my buns out of the fire! I still carry a pocket pad. In addition to all of the other documents, document training, retraining and disciplanary matters. That paper work does a great job of CYA.
