The EEOC has actively started cracking down on companies for using staffing agencies like Cognizant to replace American workers with low cost foreign visa workers. CNC announced a billion dollar deal with Cognizant a little over a month before the massive layoffs (and Cognizant is already under investigation by dept of labor for H1b and PERM fraud).
It might be a good time to send in EEOC complaints if you lost your position right after the Cognizant contract announcement (which was in the news in July). In the past EEOC has not done much but they're pushing hard for reports/tips right now AND there's a few lawyers in their comments section trying to dig into fortune 500 company violations
