NEW YORK (CNNMoney.com) - Having a pseudo-wife or pseudo-husband at work may not only make you happier with your job but may even improve your chances for promotions and raises, according to a report Friday.

Non-romantic "marriages" in the workplace are the newest craze in office romance, the New York Post said, citing a survey by Vault Inc., a career research and consulting company.

Having a support system could lead to better performance reviews and advancement, the survey said.

The firm's national survey of workplace romance said workplace "spousing" has surged in the last year, in part because it offers immediate intimacy without the sex or commitment.

"It's a wonderful support system among workers, and makes a more productive worker," Mark Oldman, co-founder of Vault, told the paper.

According to the study, 32 percent of office workers said they have an office "spouse," with many having more than one.

"They have a big attraction -- there are no strings attached, and if doesn't work out, you go pick out another office 'spouse,' and no divorce is necessary," Oldman told the paper.

There are many emotional benefits of close workplace relationships modeled after a marriage, the study said. "The 'office spouses' can be more open with each other than they can with their own spouses, and there's no guilt involved," Oldman told the paper.
