This is an article about millennials.  It seems to me that millennials have never had the opportunity to be alone, to be truly alone, for they are always in groups (including via their communications devices).  They go to daycare very soon after birth and forever after are every minute surrounded by or in contact with peers and adults - a 24/7 support system, a team.  As well, instead of encouraging self-reliance we have told them to seek help or support whenever one of life's little bumps comes along.  So it's logical that the support system continues into adulthood, including into the workplace.
