It is sleepless nights for Hyderabad's IT employees. About a 1000 lost their jobs overnight after they failed their employers' background checks. CNBC-TV18 gives the details. 
 
It has been a harrowing week for Satyam's staff, as 500 of their work mates have already been fired overnight. That is after the company conducted background checks on its middle and junior-level employees to curb fraud and minimise the risk of data theft.
 
But Satyam is not alone. HSBC too fired over 350 employees at its call centre in Hyderabad over the past week. Officials from Satyam say it is conducting checks at all its facilities in India and if an employee is found to have falsified any certification, he or she is being asked to leave immediately.

Satyam officials say they will not file criminal proceedings, but other IT and ITeS companies have begun similar checks. They hope to make their companies virtually fraud free.
