They seem to focus on this blanket ban against discussing this issue at Google, as the discriminatory act - rather than alleging that actual caste discrimination is being perpetrated at Google (for the most part).
They do however seem to point to two examples of rumoured alleged casteism at Google (I think):
"I think the Cisco case is probably the most publicly known example—is that, within a team, when you’ve got people who are caste privileged and caste oppressed, the people who are caste oppressed start to be given inferior assignments, get treated differently, left out of meetings, which are certainly things that I heard from Google employees within the company. "
"Asking things like “What’s your last name? I’m not familiar with it.” Then, when the manager hears that last name, they’re, like, “Oh, so you’re from this caste—no wonder you have these leadership skills.” Things like that. And somebody else in the room is, like, “What the hell?” It’s those different types of experiences that I’ve seen or that have been shared with me that show that caste discrimination is happening in the workplace.
By the tone of the article/employee I'm confused whether the employee is discussing hearsay based on examples of how discrimination could be occuring at Google - based on what they read about stuff at Cisco or elsewhere (perhaps with the intention of explaining why such issues could be relevant to discuss at Google) - or if they actually met Google employees facing these issues.
I wonder if the journalist themselves are trying to intentionally conflate the issues of 1) actual caste discrimination possibly taking place and 2) not being allowed to talk about casteism
Either way censoring internal talks about employee grievances/ possible workplace discrimination/discrimination outside the workplace (which one was the talk going to be about!?) is not a good look on Google - given that they've always tried to paint an image a company that lets its employees openly discuss anything for the most part.
