A US court is set to reopen a discrimination case filed by a former employee of Tata Consultancy Services (TCS) against the company in April.

The court has asserted that the case will not be rejected and asked the plaintiffs to file a "second amended complaint" by next Monday.

District judge Yvonne Gonzalez Rogers rejected a motion filed by India's largest IT firm to dismiss the allegations.

"TCS is an equal opportunity employer and bases its employment decisions on legitimate non-discriminatory policies. TCS is among the top job creators in the US within the information technology (IT) services industry," a TCS spokesperson told Business Standard.

Steven Heldt, who had filed the lawsuit against TCS in a San Francisco federal court in April, alleged that a "substantial anti-American sentiment" prevailing in the company led to his termination.

Heldt, who worked at TCS for about 20 months, had further alleged that nearly 95% of TCS's 14,000 US employees are of South Asian origin, mainly from India.

Despite being "highly skilled" with experience of around 20 years in information technology (IT), he was asked to do tasks that did not require many skills, Heldt said.

He had also accused the company of keeping him on bench while allowing the South Asian employees to do the job that was originally assigned to him.

Recently, the US government gave a clean chit to Infosys in visa violations case filed against the company. In June 2015, an investigation was ordered to probe alleged violation of rules pertaining to H-1B visa by Infosys and TCS.

"We continue to believe that there is no structural wrongdoings by Indian IT companies. The hiring made both in the US and from India (visa) are based on the talent available at a price. So far, the claims made by disgruntled employees have been proved misleading and no institutional wrongdoings against Indian IT have been found," said Shashi Bhusan of IDFC in his report.
