Jack Palmer, a former Infosys employee based in the US, has filed a new complaint against the Indian outsourcing firm and some of its executives, for supposedly wrongfully terminating his employment in 2013.
In his May 2014 complaint, filed with the US labour department, Palmer alleges that Infosys and eight of its senior executives got back at him by denying him work, bonuses and promotions and removed him from their employment, The Wall Street Journal reported.
Palmer is seeking damages for the losses he incurred in the past and may suffer in the future, alongside other costs incurred. But the compliant does not state the compensation that he is seeking, the report added.
Pursued by IBTimes UK, an Infosys spokeswoman said: "Palmer's current Department of Labor complaint is a repetition of the issues that were tried and dismissed by a [US] federal court in 2012. Palmer resigned in November 2013 and released the company from the claims he has alleged in the complaint.
"We believe this is without merit and we expect to prevail."
In 2013, Infosys agreed to pay $34m (£20m, €25m) in a settlement with the US government, which charged India's second-largest IT services exporter with visa fraud.
Infosys denied the charges but admitted to errors in filing federal employment-verification records.
The US investigation into the company's visa practices said Infosys used visitor visas or B1 visas, instead of mandated H1B visas, to send an unknown number of its employees for long-term business visits to the US.
Palmer's earlier attempt to sue Infosys triggered the probe of the IT major's visa practices. However, his case was thrown out in 2012.
Palmer had alleged that Infosys harassed him after he reported cases of possible business visa fraud.
