Whether it’s because they truly imagine a different future ofbusiness, or they just haven’t figured out how corporations workyet, a solid majority of American millennials say they won’twork for a company that lacks strong environmental or socialcommitments.

So says a new survey of 1,020 U.S. adults employed at largecompanies. The poll, conducted by Toluna, was commissioned by ConeCommunications, a Boston-based P.R. firm, and aimed towardunderstanding what employers can do to drive employee engagement.

The survey found that 64 percent of millennials said theyweren’t interested in working for a company without loftycommitments to ecology and justice, compared to 51 percent of thepopulation overall.

While it corporate altruism is only a deal breaker for half ofU.S. workers, 58 percent say they will consider a company’sinvolvement in social or environmental causes when deciding whetherto take a job. Among millennials, 78 percent say the same.

The poll found that young members of Generation X displaysimilar opinions as their slightly-younger colleagues.

“All eyes may be on millennials as the next wave of engagedemployees, but companies shouldn’t forget their managers andleaders,” says Lisa Manley, Cone executive vice president ofcorporate responsibility. “Young Gen Xers share the enthusiasm oftheir younger cohorts and are ready to invest their time, money,and personal passions to support important issues at the office andin their communities.”

Eighty-five percent of employees said that feeling that they’remaking a difference is a powerful motivator. But then again, thesame percentage reported that bonuses and gift cards would do thetrick. Perks, such as parking spacesor casual Fridays, were cited as potential motivators by 70 percentof employees.

The poll also revealed some interesting trends on how differentsegments of the workforce prefer to stay in touch with companynews.

57 percent said Facebook was their preferred social mediaplatform; no other social network has nearly the reach,particularly among the older generations. Among millennials, nearlyhalf report using Instagram, compared to less than a quarter of theoverall U.S. population.
