Ruth's Chris Steak House systematically hired undocumented workers and lets them use the Social Security numbers of previous workers, and harassed and threatened a legal worker who complained of it, a RICO class action claims in Federal Court.

The lawsuit claims that after an INS sweep of Ruth's Chris Steak House in Birmingham, many undocumented workers returned "wearing different name tags." It claims the restaurant hires undocumented workers on a "large scale," pays them in cash, knowingly accepts I-9 immigration forms containing false information, and otherwise knowingly violates immigration and employment laws.

Plaintiffs also accuse Ruth's Chris of "stealing" 20% to 25% of its workers' tips.
