Here is a fun game: Your job probably has an org chart that lets you see the employee hierarchy. Now, realize that Indian last names almost always denote cast. Understand how to discern cast from names and take a look at your org chart.
I am a white tech worker, so I didn’t think much of cast discrimination since I personally never saw even a hint of it at my job. But then I looked at our org cart and oh boy… I now am firmly in the camp that says cast discrimination should be regulated.
