Barely half of your workforce (52%) is happy at work, let alone set up for success, according to a recent workplace report by Achievers. That's chilling news, considering that successful companies depend on engaged employees.

Here's a look at factors contributing to a disengaged workforce, along with ideas for what managers can do to engage employees.

The biggest factors involve the "recognition gap," according to Achievers:

• 63% of survey respondents say they don't feel recognized for their progress at work.
• 60% say they don't feel recognized for their achievements at work.
• 60% say they don't receive in-the-moment feedback from their managers.

Yet, employees long for recognition: A whopping 85% hope to be recognized at least quarterly, if not more.
