The need to truly engage employees in their work has been gaining traction among companies. But management hasn't figured out how to do it well. And the constant inflow of millennials into the workforce will make that job harder for many employers still struggling to understand what makes this generation tick.

Those are some of the findings and conclusions from a TalentKeepers engagement study entitled "Workplace America." It's the firm's 10th annual study, and, as it notes, worker engagement continues to rise in the corporate consciousness. Survey responses from more than 700 interviewees indicated that 83 percent of companies represented consider engagement a strategic priority.

"A solid majority of American employers, 64 percent, now budget and allocate funds specifically for engagement," said Christopher Mulligan, TalentKeepers CEO. "But too few, only 23 percent, calculate the financial cost of attrition and poor engagement, a basic building block to sizing the problem and determining budgets and assessing ROI for future planning."
