Kaaren has mentioned the hand-off of responsibilities to others who are better or less qualified than the primary professionals, but it's that collaborative environment, which is synergistic, which is supportive, which provides great improvement in the safety net for patients, that is most obvious when it's not there. When mistakes are being made and recriminations and blame are being thrown about, we end up with toxic and very difficult work environments that are not good for patient care.
