We started the Top Workplaces section five years ago during the turmoil left by the worst recession in decades. The downturn had clobbered home sales, stifled tourism and crippled companies that made things. Still, our list of Tampa Bay's top workplaces was peppered with real estate companies, hotels and manufacturers. The primary question back then: How did they overcome such long odds to create a workplace their employees so cherished?Today, the economy is rebounding. Profits are on the rise. Employees, in general, feel a little better about their personal finances. So the question now is how do these top workplaces hang on to their best performers?

In: better benefits. Out: soul-sucking time clocks.
