A Nebraska woman who says she was fired for speaking Spanish at work failed to convince a federal judge that was true.

The U.S. District Judge John Gerrard dismissed Rocio Reyes’ lawsuit against Pharma Chemie Inc.

Reyes and one other woman often conversed in Spanish while working at the maker of nutritional supplements for animals and humans. The company developed its English-only policy in March 2010 because managers wanted to make sure employees understood directions.

Gerrard says Reyes failed to prove that PCI’s policy requiring employees to speak English at work was discriminatory.

And Reyes couldn’t prove she lost her job for violating the policy. The company says Reyes was laid off along with two non-Hispanic workers who didn’t speak Spanish.
