## Controversies
### Class action lawsuit in the US

On 14 February 2006, the US law firm Lieff Cabraser filed a nationwide class action lawsuit against TCS concerning payments to employees on deputation. This lawsuit was filed on behalf of all non-US citizens employed by TCS in California from 14 February 2002 to 30 June 2005. The workers alleged that they were compelled to forfeit their federal and state tax refunds to their employer and that their Indian salaries were wrongfully deducted from their US pay. On 22 February 2013, TCS agreed to settle the class-action suit for $30 million. In July 2013, Judge Claudia Wilken of the US District Court, Northern District of California in Oakland, California, granted final approval for the settlement of the lawsuit.

### Trade secret lawsuit

In a lawsuit filed in October 2014 in the US District Court in Madison, Epic Systems accused TCS and Tata America International Corp of "brazenly stealing the trade secrets, confidential information, documents, and data" belonging to Epic. This lawsuit was amended in January and December 2015. In April 2016, a US jury imposed a US$940 million fine on TCS and Tata America International Corp in the trade secret case, which was reduced to US$420 million in 2017. In 2020, an appeals court ruled that the US$280 million in punitive damages was "constitutionally excessive", but upheld the remaining portion of US$140 million in compensatory damages. The case concluded in November 2023, with TCS agreeing to pay US$125 million.

### Sexual harassment allegations

In 2019, an employee filed a complaint with the Kancheepuram labour court, alleging that Tata Consultancy Services' internal complaints committee mishandled a sexual harassment case. Despite the case being approved, there has been no significant progress over the years, with the worker accusing the company of delaying investigations. The worker has also reported unexplained transfers and other forms of alleged workplace retribution, including in performance reviews.
