Employers and staff are divided when it comes to how effective companies are at showing employee appreciation. A survey by Robert Half International Inc. (NYSE: RHI) found 89% of senior managers said their organizations were “very effective” or “somewhat effective” at recognizing employees for good performance while 70% of employees said the same.

On the other end of the spectrum, 11% of managers said they were “not too effective” or “not at all effective” compared to 30% of employees.

“Acknowledging staff just once or twice a year for their hard work isn’t enough — regularly saying ‘thank you’ or offering small tokens of appreciation can speak volumes,” said Robert Hosking, executive director of Robert Half’s OfficeTeam. “Giving kudos for a job well done seems obvious, but when managers are time-strapped, this can be one of the first things that slips. … Companies that excel at recognition combine formal programs with everyday gestures of gratitude.”

The survey included responses from more than 600 senior managers and more than 900 workers.

Robert Half’s survey comes in advance of Administrative Professionals Week, which takes place from April 19 to 25.
