Make the irregular regular: put someone in charge of it or make it a rule. TerraCycle has a C.N.O. – chief NERF gun officer – who issues NERF guns and ammo to all new employees, so they can join the periodic battles that let everyone blow off some steam. Warby Parker has an official “fun committee” to plan events, so that office fun doesn’t fall to the bottom of everyone’s to-do list. Etsy gives every new employee a $100 credit, so they can decorate their workspace. This gives everyone some creative freedom and adds atmosphere to the whole office.
