This topic is as old as leadership is. From the very beginnings of people being led, this art has been studied. People have been training, writing, and blogging about how to best communicate to those you mean to lead. The problem with saying anything to your staff is that they will always have three meanings, regardless to how much planning, thought, and good will you put into it. There will be what your words mean, what you mean by your words, and what each member of your team thinks you mean by it. It’s your responsibility to either strike certain phrases and statements from your vocabulary, or learn when the right time to use those words is.
