Does it have to be this way? Can’t resist checking your smartphone or mobile device? Sure, all this connectivity keeps you in touch with your team and the office—but at what cost? In Sleeping with Your Smartphone, Harvard Business School professor Leslie Perlow reveals how you can disconnect and become more productive in the process. In fact, she shows that you can devote more time to your personal life and accomplish more at work. The good news is that this doesn’t require a grand organizational makeover or buy-in from the CEO. All it takes is collaboration between you and your team—working together and making small, doable changes. What started as an experiment with a six-person team at The Boston Consulting Group—one of the world’s elite management consulting firms—triggered a global initiative that eventually spanned more than nine hundred BCG teams in thirty countries across five continents. These teams confronted their nonstop workweeks and changed the way they worked, becoming more efficient and effective. The result? Employees were more satisfied with their work-life balance and with their work in general. And the firm was better able to recruit and retain employees. Clients also benefited—often in unexpected ways. In this engaging book, Perlow takes you inside BCG to witness the challenges and benefits of disconnecting. She provides a step-by-step guide to introducing change on your team—by establishing a collective goal, encouraging open dialogue, ensuring leadership support—and then spreading change to the rest of your firm. If you and your colleagues are grappling with the “always on” problem, it’s time to disconnect—and start reading.

A very basic look at how cell phones work.

As seen in Time, USA TODAY, The Atlantic, The Wall Street Journal, and on CBS This Morning, BBC, PBS, CNN, and NPR, iGen is crucial reading to understand how the children, teens, and young adults born in the mid-1990s and later are vastly different from their Millennial predecessors, and from any other generation. With generational divides wider than ever, parents, educators, and employers have an urgent need to understand today’s rising generation of teens and young adults. Born in the mid-1990s up to the mid-2000s, iGen is the first generation to spend their entire adolescence in the age of the smartphone. With social media and texting replacing other activities, iGen spends less time with their friends in person—perhaps contributing to their unprecedented levels of anxiety, depression, and loneliness. But technology is not the only thing that makes iGen distinct from every generation before them; they are also different in how they spend their time, how they behave, and in their attitudes toward religion, sexuality, and politics. They socialize in completely new ways, reject once sacred social taboos, and want different things from their lives and careers. More than previous generations, they are obsessed with safety, focused on tolerance, and have no patience for inequality. With the first members of iGen just graduating from college, we all need to understand them: friends and family need to look out for them; businesses must figure out how to recruit them and sell to them; colleges and universities must know how to educate and guide them. And members of iGen also need to understand themselves as they communicate with their elders and explain their views to their older peers. Because where iGen goes, so goes our nation—and the world.
