A federal jury last week sided with Tata Consultancy Services Ltd. against four former employees who claimed they’d been discriminated against because they aren’t South Asian. Bloomberg reported the American workers had claimed the India-based IT services provider favored staffing its US offices with workers from India. The case was the first of several accusing India’s big IT firms of hiring bias in the US to go to trial; HCL Technologies Ltd., Infosys Ltd. and Wipro Ltd. face similar claims. “This is a shot in the arm for the industry, which has not seen anything positive come out on the US visa regulation front for some years,” said Anurag Rana, an analyst with Bloomberg Intelligence.
