The more you try not to think about a problem, the more it gets lodged in your brain. Here's an experiment. Don't picture Rob Campbell in a Tutu, Don't think about it, don't imagine the matching leggings and pretty ballet shoes. Go on.
That's going to ruin your weekend.
The more you try not to think about chocolate, the more the stuff gets stuck in your mind.
In other words, there's no point pretending something isn't happening, or everything's okay. It just makes it worse, rather than finding a way to deal with it.
That's what certain agencies I could mention don't seem to get. If there's a rumour, an issue or some bad news, there is absolutely no point not being straight and fair with your staff. It will only stress them out and make things worse.
