We know that teams that share values tend to knit together better. A culture in which people ‘get on’ and work for each other is considered to be productive.
Yet, tension can provide creative sparks; competition raises effort; oysters need an irritant to produce pearls.
So, don’t throw the baby out with the bathwater. Allow team members a degree of freedom in which to be ‘sparky’, create and encourage (friendly) competition and rivalry.
You will end up with a more creative workforce.
