Business executives have found staff retreats pay dividends. How much is subjective. But some suggest getaways can power employee productivity more than paid vacations.

The question is how. Sluggish employees and inefficiencies can be a vicious cycle few businesses know how to break. Yet growing evidence suggests corporate retreats — even small-scale affairs over a weekend — can lift morale and the bottom line, too.

Once considered lavish junkets, and sometimes mocked for contrived team-building ploys like trust falls, the staff retreat is making a comeback. And the reason is easier to see than your spreadsheet trend line: Companies are figuring out how to have fun.

To start, get rid of the PowerPoints. Encourage your employees to get out of the weeds and discuss big-picture ideas. Throw out some new goals and find a way to foster brainstorming. Don’t worry about splurging on a big-name guest speaker. After all, you’ve invested in your employees — harness the innovative thinking from them.

Make sure to stage your retreat in a relaxing setting. Those office walls can get pretty confining, no matter how many modern colors you paint them. If you want your workers to clear their heads and think differently, place them in an atmosphere that puts them at ease. Think seaside, relaxation and foamy surf!

Ultimately, the goal is to give your staff a fresh perspective by putting them in a new environment where they can try new things. Kinda like a vacation.

They’re rich, famous, talented — and, they’re crusading for a good cause, too. Seven pop stars have emerged in the fight against bullying. Before looking, can you guess who’s on the front lines of the cause?

In the No. 1 spot on the list released by Policy Mic is none other than Lady Gaga, who started the “Born This Way Foundation” two years ago to “foster a more accepting society, where differences are embraced and individuality is celebrated.”

When a 14-year-old Gaga fan committed suicide after being victimized by bullying, Gaga took the news hard.

“The past days I’ve spent reflecting, crying, and yelling,” the star wrote on her Twitter feed shortly after the death of Jamey Rodemeyer. “I have so much anger. It is hard to feel love when cruelty takes someone’s life. Bullying must become illegal. It’s a hate crime.”

Canadian sensation Justin Bieber came in at No. 4 on the list. His song “Born To Be Somebody” was used in the trailer for the documentary Bully. Bieber says he wanted to contribute to the documentary because he’s experienced the meanness spurred by bullying first-hand.

“I was bullied,” Bieber told Showbiz Tonight. “Most people in their lifetime have been bullied at some point. I think it’s about time that people start making a change.”

Lady Gaga and Justin Bieber are just two of seven stars committed to the cause. To read about the other five celebs who are using their fame for good, check out the list here.
