What do a lot of your co-workers secretly want from you and the boss? Probably a “thank you!” That’s according to a new study that discovered workplace gratitude is at an all-time low – which can do everything from increase employee turnover to hurt company profits.

Researchers surveyed 2,000 people, asking them who thanks them – and who they thank – on a daily basis. Everyone from co-workers to family to the mailman!

The result? The people we’re least likely to thank are our coworkers! In fact, just 10 percent of us thank a fellow employee every day, and only 7 percent thank our boss every day. Meanwhile, we’re 4 times more likely to thank our spouse, kids, a salesperson, the mailman, or even an acquaintance over a co-worker.

So, why aren’t we more thankful on-the-job? Researchers say it’s because we take our cues from the boss. If they’re appreciative, then that grateful attitude trickles down through the company culture and we’re more likely to thank each other. But if the boss never says “thanks,” then odds are we’ll pick up that negative attitude.     

One big reason a lot of executives don’t thank their workers is because they think a “thank you” is like saying “Please take advantage of me.” In fact, the survey found that more than 1 in 3 managers are scared that showing any gratitude will cause their employees to develop an ego, or ask for a raise.

Plus, most bosses think that employees are already thanked every week – in the form of a paycheck! But a thankless atmosphere can have major repercussions. A study of 800 human resource managers found that worker appreciation is great for the bottom line. Because employees who feel appreciated are often much more productive and loyal to their company than those who don’t feel appreciated.
