But was there some disconnect between the Tata group and Vaishnavi after the tapes were made public?
Radia declined to talk for this article.
But there are some pointers.
Last year, a few weeks after the tapes had become public, a team of senior Tata executives went to media houses to get their assessment of how the Tata name had been dented.
There was nobody from Vaishnavi in that team.
Subsequently, Ratan Tata said in a television interview that while there was no conflict between his group and Mukesh Ambani's Reliance Industries at the moment, there could be one in the future: telecom.
So, Radia has to take a call.
"Tata defended his group but he never defended the conversations Radia had, many of which were industry issues," says a senior government official.
"Radia was not working for us alone," Tata told the Public Accounts Committee of Parliament. "She has been a supporter of Raja in many ways."
Thus, in her email to her employees, while Radia mentioned that Reliance Industries would absorb 30 of them, there was no such commitment from the Tata group, though some insiders say that it may absorb some members of her team.
Radia's contract with Reliance Industries, incidentally, had two more years left.
