Unfortunately, too many people feel the point of CRM skills is to share authority. It is not. The point of CRM teaching is to lessen the authority gradient, especially between older Captains and younger inexperienced crew members, so that safety is enhanced by 'juniors' feeling confident enough to speak up and voice their concerns. The law is quite clear that only one person - the aircraft Commander - has overall responsibility. Sharing the workload efficiently is one thing, but sharing authority is definitely not the purpose of CRM.
Often those who think that their CRM skills are very high, are those that require further education in inter-personal relationship.
I prefer the 'KISS' philosophy myself - 'Keep It Simple Sucker': it makes for an easier life and a safer one!
