The title is a reference to a character in a TV comedy sketch show ("The Fast Show"). If you haven't seen it, this character was the dad of two small boys, who was constantly playing games with them (eg cricket), but instead of helping them get better at the game or get satisfaction out of playing, he would simply try to show them how good he was by trying to win. Eventually they would always just abandon the game to talk to mum, leaving him still desperately competing, but completely ignored by them. Very funny, partly because although it's a caricature, we've all seen that behaviour - though obviously never done it ourselves!
It came up as the perfect way for one of my clients to describe their boss - or at least the experience of working with them. As you can imagine, they weren't very motivated! I won't go into all the work we did from that, but it was a helpful image to allow them to engage with the boss rather than just withdraw, to overcome their feelings of inadequacy, and to have an adult to adult conversation with their boss about the dynamic of their interaction.
It's not an uncommon problem. Marshall Goldsmith, in his book "What got you here won't get you there", lists "Twenty habits that hold you back". Number 1 is "Winning too much" and number 2 is "Adding too much value" - which is another way of showing you can always do better than others. They are fantastic traits on the way up. They can be real problems when your job as a leader is to make everyone else do better, ie make them winners. I'd recommend the book - the title alone is worth having on your bookshelves as a constant reminder!
