Intel has been a star in the technology world for nearly half a century. One secret to its success is a little more spiritual than you might have guessed, according to CEO Pat Gelsinger. In a recorded message that will play during an international conference on business and religion this week, Gelsinger highlights the competitive advantage that comes from building a culture that celebrates personal faith alongside other employee traits. At Intel, workers are free to "bring their entire self" to the office, he says.
