I do not disagree with you. The (high) morale of any "unit" has implications on said unit's success; likewise, (low) morale has negative affect on the operation. Again, I am not arguing with your correlation between morale and (unit) success.
With that being said, many moons ago, when I was a young officer in the Army it was instilled in us the required tenets of an Army Officer(leader). These included, Loyalty, Duty, Respect, Selflessness, Honor, Integrity and Professionalism (Acronym:
LDRSHIP).
You asked me if I thought a "professional is expected to go above and beyond?" In reality, each person's glass has varying levels of
fullness depending on their
thirst. Does that make sense?(no sarcasm intended) One person's "above and beyond" might be another person's "professional" duty as a Commercial Airline Pilot, performing their fiduciary duty, under the current contract (PWA) with said employer.
Standing by for incoming.
