Hiring employees isn't enough to keep your small business running; you also have to keep them. Turnover rates are the silent killer. They're not as obvious as weak customer reception, but they're just as deadly. Every employee you lose represents cost and lost value: cost, because you'll have to spend on finding and hiring a replacement; lost value, because you're not getting the expected return from your investment in hiring them in the first place. Fortunately, there are plenty of things you can do to keep retention high and turnover low.
