If you’re thinking of cutting your midlevel managers in the new world of work, think again.

Middle manager. The term evokes a bygone industrial era in which managers functioned like cogs in a vast machine and bureaucracy ruled. In recent decades, midlevel managers became a favorite target for the chopping block-underappreciated, often considered a superfluous layer of the organization. This view is so widespread that it has seeped into the identity of the managers themselves.

Not only does this outdated perspective need to change, the future demands it. In Power to the Middle, McKinsey thought leaders Bill Schaninger, Bryan Hancock, and Emily Field call for a profound reimagining of what middle managers can and must be able to do. They explain how middle managers are uniquely positioned close to the ground but with a crucial connection to company strategy-enabling them to guide organizations through the current period of rapid and complex change, as well as help to shape the new world of work.

The authors compellingly articulate this profound shift in the workplace, showing how:

As the war for talent escalates, managers are an organization’s first line of defense, requiring strong people skills to attract and retain the best talent. Middle managers possess the granular knowledge and perspective necessary to lead the realignments resulting from digital disruption. Managers must shift from merely enforcing rules to challenging them, serving as the critical stopgap for rules that are ineffective or obsolete. Crucially, good managers must not be promoted out of their jobs; instead, their title and compensation should reflect their high value and allow them to advance within their roles.

With rich stories and cutting-edge research, Power to the Middle offers a new model for companies to radically alter the way they hire, train, and reward their most valuable asset: managers, the true center of the organization.
