The enterprise technology company announced on Wednesday it would cut 5,500 jobs, or 7 percent of its global workforce, starting in fiscal year 2017, as it restructures to focus on key priority areas such as security, internet of things, collaboration and cloud services.
Though the layoffs were fewer than the 14,000 some had speculated, the stock tumbled as much as 1 percent in extended trading, after closing more than 1 percent lower in Wednesday's regular session. In early trading Thursday, it was down less than 1 percent.
"Any time we make these decisions, we do not make them lightly," Robbins said in an interview on "Squawk on the Street."
"I think that for the reports to get out ahead of our announcement, frankly, I think, are a little irresponsible. We're talking about people's lives here," he added. "I think there was even an insinuation that we may have leaked that, which is just insulting, frankly. We would never do that before we had an opportunity to speak to our own employees."
