A new study found that treating your employees with respect makes them more resilient. Before you respond with, “Duh,” consider this …

The fact that this study had to be done suggests too many managers have yet to internalize this basic truth, says Jessica Stillman in an article for Inc. The study, which includes responses from more than 1,000 young Americans by a team of researchers out of Kansas State University, revealed that when bosses are respectful to their employees, those employees like their jobs more and are more resilient. The next logical step: they stay with their organizations, saving those orgs time and money.

Study participants who felt they were respected and valued both by colleagues and by bosses were more likely to experience occupational resilience — that is, they were more able to deal with the challenges of the workplace. In turn, greater occupational resilience led these people to say they were more likely to want to stay employed at their company and more willing to engage with their roles.

A belief that snapping at and pressuring young employees is either an acceptable way of unloading your own stress, or somehow brings out their best, persists in too many workplaces.

So let this study serve as a handy reminder from science. None of those things are true. Putting up with gruffness from bosses isn’t young employees “paying their dues” professionally. It’s bosses undermining their teams’ ability to perform at their best.

And, happily, the reverse is also true. Something as simple as saying “please,” “thank you,” or “nice job” can make employees markedly more resilient and engaged.
