The Indian caste system is affecting the lives of Dalit tech workers in the US, with over 90% of Indian techies in the US being upper-caste Indians. A recent lawsuit against Cisco alleges that an upper-caste Indian manager discriminated against a Dalit engineer. The lawsuit highlights the issue of caste-based discrimination in the US tech industry. The article also mentions that many Dalit tech workers have reported instances of harassment, humiliation, and career-halting interventions by high-caste Indians.
