The oldest Millennials are now well into their 30s, and they're increasingly running companies. Inc. and our sister publication, Fast Company, partnered with career-development site the Muse to survey 155 Millennial bosses to see how they manage, what they value, and how they plan to shape the future of business. The top priorities they cited are humanist: creating positive work cultures, forging strong relationships (in person, not through apps), and caring for the whole person, not just the worker. And, unlike some Boomers and Gen-Xers, they're optimistic about those who will replace them. As Elena Valentine, co-founder and CEO of video company Skill Scout, predicts, "I have a hunch Gen Z is going to make an even bigger impact."
