Overqualified employees often pose a flight risk, but there are ways to keep them in place, according to Berrin Erdogan, professor of management at Portland State University, who has run several studies on overqualified employees.

In general, workers who think they are too good for a position are probably already looking for a new one. "Those who are objectively over-educated for their jobs also are likely to change jobs more quickly," says Erdogan in a recent reddit Ask-me-Anything question and answer session.
