This is one of the coolest counterintuitive ideas I've heard in a long time. It's gotten some play in the blogomedia, but it's still worth pointing out. The advice for companies goes like this:

Pinpoint the least committed of your new employees by offering them $1,000 to quit. The ones who take this early buyout after only a few weeks on the job will be the ones you don't want in the long term.

Details here, courtesy of Bill Taylor, former Fast Company editor, who writes in Harvard Business Review about the hiring practices of Zappos, the legendary online shoe company. He says:

[Zappos] is a company that’s bursting with personality, to the point where a huge number of its 1,600 employees are power users of Twitter so that their friends, colleagues, and customers know what they’re up to at any moment in time. But here’s what’s really interesting. It’s a hard job, answering phones and talking to customers for hours at a time. So when Zappos hires new employees, it provides a four-week training period that immerses them in the company’s strategy, culture, and obsession with customers. People get paid their full salary during this period.

After a week or so in this immersive experience, though, it’s time for what Zappos calls “The Offer.” The fast-growing company, which works hard to recruit people to join, says to its newest employees: “If you quit today, we will pay you for the amount of time you’ve worked, plus we will offer you a $1,000 bonus.” Zappos actually bribes its new employees to quit!

Why? Because if you’re willing to take the company up on the offer, you obviously don’t have the sense of commitment they are looking for. It’s hard to describe the level of energy in the Zappos culture—which means, by definition, it’s not for everybody. Zappos wants to learn if there’s a bad fit between what makes the organization tick and what makes individual employees tick—and it’s willing to pay to learn sooner rather than later. (About ten percent of new call-center employees take the money and run.)

Indeed, CEO Tony Hsieh and his colleagues keep raising the size of the quit-now bonus. It started at $100, went to $500, and may well go higher than $1,000 as the company gets bigger (and it becomes even more difficult to maintain the all-important culture and obsession with customers.)
