Never went in at night for a surprise visit at last facility as I never once even heard a whisper of a problem & all the work indicated they were on top of things.
New place....sounds like I'll need to make a surprise visit at least monthly. According to the rumors I will find several sleepers. Had a meeting in just last couple days to warn charge nurses that if I come in and find this I will immediate terminate any sleepers and potentially charge nurses as well for allowing it to happen. Interestingly enough, no one denied this during my lecture (but there will some "Oh crap" faces).
