You might expect Yahoo to be suffering from recruiting and retention troubles these days, given its recent layoff and Microsoft's offer to buy the Internet company in February. But attrition has not increased at the Sunnyvale, CA-based company since the Microsoft offer, Yahoo said in late March. Yahoo, a pioneer on the Internet, has weathered turbulent times over the past year, including the departure of CEO Terry Semel and slumping profits. Another major source of upheaval was Microsoft's unsolicited bid to acquire Yahoo for $44.6 billion in cash and stock. Microsoft has been quiet recently regarding the potential deal. But the offer remains on the table.
