The country's third largest software exporter Wipro today said it will hike salaries for its employees in India by 12-15 per cent as it looks to counter high attrition.

The wage hike, effective June 1, will be to the tune of 2-4 per cent for onsite staff (at the customer site).

Announcing Q4 2010-11 results, the company said wage hike will impact its operating margins in the first quarter this fiscal.

Wipro, which has been competing with domestic and global rivals like Tata Consultancy Services and IBM, has witnessed high levels of attrition over the last few quarters.

"We have announced wage hikes effective June 1, 2011, which would have an impact on the operating margins... It will be 12-15 per cent for offshore and 2-4 per cent for onsite employees," Wipro Executive Director and Chief Financial Officer Suresh Senapaty said.
