Many good workers feel underappreciated by their employers, even when they work hard and produce quality results, a recent survey found.

Of more than 500 full- and part-time employees surveyed nationwide, 35 percent said the company they worked for was ineffective at rewarding strong performance, according to OfficeTeam, a Menlo Park, Calif.-based staffing services firm. At the same time, 30 percent of 150 senior executives surveyed admitted that employee recognition wasn't a high enough priority.

"Rewarding employees for their accomplishments enhances productivity, reinforces positive behavior, and builds staff morale and loyalty," Diane Domeyer, executive directory of OfficeTeam, said in a statement.

Domeyer said employers who fail to reward quality work risk losing employees to competitors. She said rewards could be as simple as offering extra days off or extended lunch breaks, or the option of working on desirable projects.
