The Great English Divide

How much is English worth? In jobs from offices to the factory floor, recruiters say that workers who speak English often command salaries 25% to 35% above those who don't. More important, they can aspire to a host of higher-level jobs that are off-limits to monolinguists. "English is an imperative," says Didier Vuchot, chairman of recruiter Korn/Ferry International in Europe.
