Tata Consultancy Services (TCS) announced that its employee attrition rate continued to rise during the January-March quarter, reaching 17.4%. "The reported attrition number of 17.4% will get worse for the next couple of quarters just because of the way LTM attrition is calculated," CEO Rajesh Gopinathan said. "But...on a month-on-month basis...we're starting to see flattening of it," he added.
