Why are there almost no updates or least/no reported incidents coming from the Chennai office?

It's Tamil company that's why. Tcs means Tamil consultancy services, mostly all CEOs and senior management are from Chennai only. Chennai also has the maximum number of offices and work force reporting. Besides they want to terminate from the other locations so that at the end the Tamil people are more in the company. It's sadly the number saying the story, and nothing official in this.

My boss C5 was ket go today from chennai.

Haha, maybe they are saved
