5 Companies That Had A Rough Week

Polycom wasn't the only IT vendor this week whose CEO unexpectedly stepped down. Juniper Networks revealed Tuesday that CEO Kevin Johnson planned to retire and a search for a new chief executive was already under way.

The surprise announcement, which Johnson described as a personal decision, came just prior to Juniper's second-quarter earnings call where the company reported 7 percent growth to $1.15 billion.

Johnson, Juniper's CEO since 2008, will stay in the post until his replacement is named. Johnson's departure comes on the heels of several other high-level executive departures from the company this year.
