Professionals may not believe their manager is helping them succeed, according to the results of a new survey from Korn Ferry.

The survey showed that 58% of those surveyed say their manager does not help them advance their career. Nearly half, or 48%, say their boss has taken credit for something they’ve done, and 39% say that their boss at some point has “thrown them under the bus” (betrayed them).

Meanwhile, 35% say they consider their boss as a friend.

While 65% of professionals say they do learn from their boss, 56% say that their boss motivates them to little or no extent.

Dennis Baltzley, Korn Ferry’s global solution leader for leadership development, commented, “Many professionals have complicated relationships with their managers. While most are eager for their boss to help them learn and grow in their careers, the reality is many time-strapped and career-stressed bosses often don’t make the effort to nurture their direct reports.”

“Communication gaps have been at the center of management and direct report disconnects since the beginning of time,” Baltzley said. “Managers often feel they are communicating a great deal, and direct reports feel that they don’t have enough context or information.”

The survey also showed that 40% of professionals think they could do their boss’s job better than the boss, meanwhile 32% would actually want the job.

“It’s also important that professionals understand that support from their boss is not the only path to success,” said Baltzley. “Researchers point to the 70-20-10 rule, where 70% of what you learn is from on-the-job experiences, 10% is from formal academic learning, and 20% is from relevant other people, such as a boss. It’s critical that professionals chart their own career.”
