The rate of attrition, which fell considerably in the last two years due to the IT slowdown, is once again raising its ugly head, say industry experts. Growth in volumes and rapid scaling up of offshore development centers (ODC) by multinational companies has once again made attrition a key issue in the Indian information technology (IT) space. Companies such as Infosys and Wipro have seen their attrition rates go up during the last few quarters. Mid-sized companies have also seen attrition go up significantly. Polaris Software Lab has seen its attrition rates rise to 14 percent after the merger with OrbiTech Solutions. The most obvious way companies are dealing with the rising attrition rates is through salary hikes, among other measures.
