"The collective impact of these factors will throttle the hiring action by more than 20%." With an attrition-linked replacement hiring of more than 120,000 the total hiring churn of these companies was 210,000 last year, Karanth added. TCS reported a record low 7.2% attrition rate in the fourth quarter of the previous fiscal year, the attrition rates rose sharply for Infosys and Wipro. Both the Bengaluru-based companies confirmed that there would be a further increase in attrition and that they were undertaking measures to retain talent. "The attrition is likely to remain at this level for the next one or two quarters," Rao of Infosys said. The near 15% attrition rate is at the high end of the company's average and is higher than the previous quarter. "With compensation intervention, promotions and other initiatives we are confident of sustaining it at this level… This year (FY21) we added 21,000 employees from campuses globally and we plan to add 25,000 from campuses this year," Rao said.
