Open and honest communications between employers and their staff can boost both morale and productivity, according to a recent study by Deloitte.

Seventy-two percent of more than 4,000 employees surveyed by Princeton, N.J.-based Opinion Research said bosses that are more honest about their needs, such as taking time off for personal reasons, can lift staff morale and create a more productive environment as a result. Another 84 percent said openness from management promotes workplace ethics, the survey found.

More than half of the employees surveyed said they notice when their boss has different standards for themselves and their workers.

"By promoting open and honest communications across organizations and setting the tone at the top, our survey tells us that the workforce of today can be motivated in different ways," Deloitte Chairman Sharon Allen said in a statement.
