Language discrimination

A "speak English only" policy in the workplace can be seen as a form of language discrimination. This is because it limits employees' ability to communicate in their native language, which can lead to exclusion, misunderstandings, and a lack of diversity in the workplace. Such policies can be seen as discriminatory because they target individuals based on their language ability, which is a protected characteristic under employment discrimination laws in many countries.
