Once upon a time there was a man named Mao Zedong...
He wrote a little red book for his Chinese comrades on how to be a good mate. The page went very wrong, but the idea of the little red was good enough. Our employee handbook is barely red, but the purpose is a bit the same. A book about who we are, what we do, and how we do it. But also vice versa. Who, what and how we are not.
