A taxi company instituted an English-only policy for its dispatch office. All of the employees spoke English, although some spoke Spanish as well. The memo announcing the policy stated that “there is to be no Spanish spoken in the main office” unless a customer did not speak English. The policy applied to business conducted in the main office, but not to conversations outside of the main office during breaks. Violations of the policy subjected employees to termination. The employer claimed that the policy was needed to help cut down on miscommunication between drivers and dispatchers. Is this English-only policy discriminatory?
