There can be tension when one of your peers has been put into a position of authority, particularly since "millennials value equality more than hierarchy," as Karsh says.

Aside from this, Gen Y workers tend to have a harmonious relationship with a Gen Y boss. "It could be a beautiful match, because they probably feel similarly about working methods," Karsh says. The like-minded colleagues have to recognize how these characteristics affect a person in a management position. "Millennial managers feel that to be successful, they must also share 'the why' behind what they're doing as a manager," McDaniel says.
