Despite layoffs and the controversy surrounding her elimination of telecommuting privileges, Marissa Mayer’s been good for Yahoo’s workforce. In releasing the company’s second-quarter results, the struggling Internet pioneer’s chief noted that more employees are sticking around than bolting and some of its former workers are coming back into the fold. In May, for example, Yahoo received 10,000 resumes, Mayer said. Ten percent of its second quarter hires were former employees. But most dramatically, year-over-year attrition decreased 59 percent. “The energy and excitement on campus is incredible,” Mayer tweeted in releasing the second quarter results. Indeed, the company says the quarter was one of the most productive in its history as it worked up to launching nearly one product a week. After just a year in the CEO’s office, Mayer appears to be hitting her stride. Although Yahoo’s end to telecommuting raised more than a few hackles, any outrage was tempered when the company unveiled a generous maternity leave policy for its female employees, doubling the paid time off for new mothers to 16 weeks. Fathers, it should be noted, weren’t as well-treated – they receive half that paid time off. And employee morale seems on the upswing, despite Mayer’s cutting 1,000 jobs during her tenure. That’s good news for Yahoo, too, as it focuses on its key growth areas - mobile, search, display advertising and video. There’s a lot of competition for mobile app developers especially, employees who Yahoo likely wants to keep close at hand.
