Answer:
Institutional discrimination.
Step-by-step explanation:
The term institutional discrimination covers a wide range of discrimination or prejudiced acts that are occurring in a place of employment or any form of an institution as a whole. It can cover a type of discriminatory act within a group of employees to a team.
According to the given statement, if a workplace requires or asks its employees to use only English as a tool of communication, while there is no such necessity to restrict the use of any other language, this is a clear form of discrimination in the institution. The restriction on the workers to adhere to a single language to converse thereby discriminates against those who are not fluent in the said language.
