Facing a tighter labor market, more employers are boosting efforts to retain good workers, recruiters say.

In a survey of 600 employers by Washington, D.C.-based employee retention research firm TalentKeepers, 81 percent said talent retention was an important part of their human resource strategy, twice as many as a year ago.

The full study, to be published next month, found 40 percent of employers surveyed said they expected turnover rates to increase in the months ahead, compared to 21 percent who said they would decline.

"It's great that executives finally view retention as not only an HR priority, but as an important business priority that affects company performance and the bottom line," Craig Taylor, VP of Client Services for TalentKeepers, said in a statement. "This opens up the dialogue about retention strategies that can be measured in relation to performance and financial goals."
