It would be naive to assume that a group of people can work together in perfect harmony. There are going to be times when someone feels they have been wronged. In these times the following procedure should apply:
Team members are encouraged to self-mediate all disputes. In all situations, treat 'wounds' appropriately. A prick on the finger just needs a tissue for a couple of seconds. Some grazes and cut just need a Band-Aid to help heal well but will probably heal anyway if left untouched. More serious lacerations need immediate intervention for survival. If a wound is left to attract an infection then the obvious threat of gangrene is present.
