If you'd like a raise or need to close a business deal, you should use eye contact and positive body language to get what you want.

If that doesn't work, try hiring a hostage negotiator.

Yeah, that should do the trick.

Chris Voss Teaches the Art of Negotiation is a new MasterClass from a former FBI lead international kidnapping negotiator. It's live now and ready to impart some powerful wisdom.

In the classes, Voss draws from his FBI past and recounts how he handled high stakes negotiations, including how he worked to secure the release of American journalist Jill Carroll, who was kidnapped by Al Qaeda in 2006. And his work on the 1993 Chase Manhattan bank robbery in Brooklyn, in which you'll hear tape recordings from the phone calls he had with the hostage takers. 

Throughout the 18 lessons, Voss will show how some of these field-tested tools from his hostage negotiation days can be easily implemented in everyday life to achieve goals and strengthen relationships. You'll learn communication skills and bargaining strategies, including tools such as mirroring, labeling and posing calculated questions. He'll also show you how to read body language and detect speech patterns, and how to bend someone's reality to your way of thinking. 

Those practical tactics can be applied to everything from getting better service at an airline counter and securing a late check out from a hesitant hotel clerk to negotiating a raise at work and convincing a family member to see things your way. 

Hopefully you'll never need to talk someone down off a ledge or navigate a hostage situation.

But it's nice to know you can.
