It's easier than ever to listen in, to hear what your customers say about you, to read what your friends are posting, to eavesdrop. Keep surveying your employees, tap their phone lines, hang out in a stall in the break room…
If you try hard enough, you can hear what people are saying about you behind your back.
The thing about the fly on the wall, though, is at the end of the day, he spends a lot of time eating dung.
What people say isn't always what they mean. It's more productive to watch what they do.
