Over the last few years we've tried some interesting things to help companies engage their employees, a few we've invented, others we've learned from the smart people we hang out with. Some have worked brilliantly, some have been okay and others have failed spectacularly. We'd like to share some of the principles and practices that have worked out well for us and our clients and we hope they help you, but more importantly we'd like to save you from some of the horrible blunders that we've made (legal restraints mean we can't talk about them but we'd just like to say that we're really sorry Stuart, we're sure your hair will grow back).
