Two employees at a Whole Foods Market store in Albuquerque say they were suspended last month after complaining about being told they couldn’t speak Spanish to each other while on the job.

Bryan Baldizan told The Associated Press he and a female employee were suspended for a day after they wrote a letter following a meeting with a manager who told them Spanish was not allowed during work hours.

“I couldn’t believe it,” said Baldizan, who works in the store’s food preparation department. “All we did was say we didn’t believe the policy was fair. We only talk Spanish to each other about personal stuff, not work.”

He said Whole Foods officials told them about company policy and issued the suspensions.

Ben Friedland, Whole Foods Market Rocky Mountain Region Executive Marketing Coordinator, said the Austin, Texas-based company believes in “having a uniform form of communication” for a safe working environment.

“Therefore, our policy states that all English speaking Team Members must speak English to customers and other Team Members while on the clock,” Friedland said in a statement.

“Team Members are free to speak any language they would like during their breaks, meal periods and before and after work.”

Friedland said the policy doesn’t prevent employees from speaking Spanish to customers who don’t speaking English nor does it prevent them from speaking Spanish if all “parties present agree that a different language is their preferred form of communication.”

Whole Foods Market spokeswoman Libba Letton told the AP that in addition to safety reasons, the policy is in place so employees who don’t speak Spanish don’t feel uncomfortable.
