There are always some major sporting events going on somewhere in the world. If you have teams of agents try linking them to the events for some fun. For example with say the World Cup football championships, give every team in your contact center an identity of one or more (if you have less teams than those competing in the championships) of the competing football teams. Then, as the championships develop give your winning teams (corresponding with winning football teams) some extra perks or small prizes. When it comes to the finals have some better perks or prizes. A little fun goes a long way to help motivate your staff!
