CHARLOTTE, NC: November 28, 2016. In an article published shortly after the election of Donald Trump to be the next U.S. president, the 14th Dalai Lama, Tenzin Gyatso noted: "We all need to be needed".

He went on to say that such a desire "does not entail selfish pride or unhealthy attachment to the worldly esteem of others" but is a natural human hunger "to serve our fellow men and women".

Is there a link between service to others and corporate success? The continued profits of Deutsche Post DHL, FedEx Corp. and the United Parcel Service would seem to suggest there is.

"Volunteerism has always been an integral part of our company culture," says UPS CEO David Abney. The company has pledged 20 million hours of volunteer service by the end of 2020 as a "commitment to our volunteering and philanthropic efforts that advance and enrich communities around the world".

FedEx Cares launched its volunteer program in 2005 and has since expanded it to 200 U.S. cities and 120 countries. "This spirit of giving embodies what FedEx Cares is all about – making the world a better place," says Neil Gibson, vice president of Corporate Communications FedEx Services.

The Deutsche Post DHL Group launched its 'Global Volunteer Day' in 2008. By 2015, over 110,000 employees were involved in providing support to non-profit projects, contributing more than 260,000 volunteer hours in 114 countries around the world.

Citing scientic studies, the Dalai Lama says that Americans and Germans who prioritize doing good for others, or who seek to serve society, are much more likely to be happy than those who do not view service as important.

So for at least three corporate infuencers, such employee happiness seems good for business.
