How did so many eggs get in this basket?
Don’t put all of your eggs in one basket. That old saying warns us to diversify our investments. Great teammates shouldn’t have a problem helping out another teammate. The danger comes when that help becomes expected and the less faithful and competent take advantage of the capacity of the faithful few. This is a huge morale killer as injustice is abided over time and most of the work is done by a small number of people on the team. Teams that allow this have lost the benefit of a team, have failed to diversify their investments and instead have bet everything on the ability of a few individuals.
