If you're coming up with a list of management challenges to tackle this year, make sure to include employee burnout, a growing issue that is slowly crippling workforce retention.

That's according to a new study conducted by workforce solutions company Kronos, in partnership with consulting firm Future Workplace. Going into 2017, 87 percent of the 614 surveyed HR professionals said that improving employee retention was a high or critical priority.

Some of the most common reasons for burnout, respondents said, are unfair compensation, unreasonable workload, and too much overtime. They also cited outdated technology and barriers to success caused by a lack of organizational and executive vision. While these factors can fall outside of an HR manager's control, a quarter of respondents pointed to problems they do have power to fix, like poor management styles, a negative workplace culture, and a perceived disconnect between a worker's role and corporate strategy.

The broader solution is simple: Better communication. It's important to remember that most people, especially managers, are focused on completing the tasks by which they are evaluated. Setting aside time to brainstorm different strategies to improve team morale rarely seems to be a priority. The role of an HR manager is to make it easier on them by providing ideas for team bonding activities--even if it's a simple happy hour. And you can show employees appreciation by reminding them how their role fits into the organization's big-picture vision.
