Michael Blowhard points me to the 612% rise since 1996 in EEOC lawsuits against employers mandating English Only workplaces.

Claims against workplace English-only rules have increased 612 percent, from 32 cases in 1996 to 228 in 2002, according to the U.S. Equal Employment Opportunity Commission.

But they're still only a fraction of the EEOC's 9,000 annual claims of national-origin discrimination.
