My dad recently told me how during the 1980s they had two Indians working together on a project. Turns out one of them was upper-caste, and the other lower-caste, and the upper-caste basically refused. Was impossible to work with, because he was offended that he had to work with a lower-caste person. If this attitude discrimination of Dalits by upper-castes is really so common in non-Indian companies, it sounds like…
Even trying to embarrass them in a meeting didn't work. With all eyes on them they would just look at me with a look of mild surprise. They simply (and sincerely) could not acknowledge why someone would phrase as a criticism something that for them is so naturally correct. For them it looked like criticizing a farmer for using work horses. I found this as some of the most disgusting behavior I have ever witnessed in a place of work.
