Harvard University has added caste as a protected category for all graduate and undergraduate student workers. The historic addition marks Harvard as the first Ivy League school to have caste equity protection in its non-discrimination clause for unionised student workers. This decision will impact more than 4,900 student workers at Harvard and the surrounding Harvard community, Equity Labs said in a statement.

With this addition, Harvard joins UC Davis, Colby College, Brandeis University, and several other universities where students, faculty, and staff face caste-based discrimination, Equity Labs said.
