According to sources close to the situation, Microsoft CEO Steve Ballmer is likely to unveil his plans to restructure the tech giant to a larger group of senior execs by July 1. That prospect has many top managers at the company worried, since Ballmer has been making these significant plans with limited consultation with the wider leadership group at the software giant. Instead, he has been working with only a small group of his direct reports and also some Microsoft board members, numerous sources said. That has meant that most senior execs have largely been left out of the decision-making process related to Ballmer’s goal of solidifying Microsoft into the “devices and services company,” that he wrote about in his annual shareholder letter last October. The impending changes — and the lack of information about them — has made for some level of discomfort inside Microsoft.
