Anecdotally, we know that happier employees are more likely to work harder and to care a lot about their jobs. But research shows that’s the case, too. According to a study by the University of Warwick, happy workers were about 12 percent more productive than unhappy ones.

What’s good for the soul it seems, is also good for business. So without further ado, let’s get to the office merrymaking.

1. Puzzles. Always have one going in the break room. They provide quick mental relief from mind-encompassing work projects, and they’re cheap.

2. Games. Take a break to play miniature croquet or desktop skee ball, or get the whole office involved in a heated round of cat bingo.

3. More games. Install an indoor basketball hoop for some impromptu fun.

4. Snacks. Whether it’s a dozen doughnuts, a barrel of cheese balls, or something a little healthier, everyone loves free food. Especially at work.

5. Ditch the conference room. Have a staff meeting off-site. Try a golf course, an art museum, a restaurant, a hotel, or a spa.

6. Quality caffeine. Say goodbye to the not-so-good office coffee maker and splurge on a fancy espresso machine. Your employees will thank you very energetically.

7. Allow dogs. One dog can improve an entire office’s mood by 89 percent. We have no scientific evidence to prove this, but who’s really going to argue?

Get two office dogs, and you’re in unprecedented happiness territory.

8. Plants. You don’t have to go full Amazon spheres with this one. Just add a little greenery to the conference room and set a succulent or two on your desk.
