When it comes to workplace relations, a little appreciation goes a long way.

In his new book, The 5 Languages of Appreciation in the Workplace, Gary Chapman explores the many ways businesses can make employees feel appreciated.

The book is a follow-up to Chapman's successful series, The 5 Love Languages, and breaks appreciative workplace gestures into these categories: Words of Affirmation, Quality Time, Acts of Service, Tangible Gifts and Physical Touch.

"There are appropriate touches in the workplace," Chapman says of that final category, which he admits could be controversial. "A high five, a pat on the back, a firm handshake."

Though the most obvious sign of appreciation — a big raise — is always nice, Chapman, who coauthored the book with Paul E. White, says in today's economic climate many companies need to find other ways to reward workers. "Many companies are just trying to survive, and there's really not money there to give raises or bonuses," he explains. "Then understanding the person's language of appreciation is very important, because most of these do not require money."
