Dang. Everything was going well for Sun this week until it executed a classic case of PR foot-in-mouth and stuffed everything up. The big business news today is that Sun’s laying off 1,000 workers in an effort to regain profitability. It’s not likely to significantly impact the company’s ability to deliver on this week’s impressive news, but it sure does see the return of the dark financial clouds that persistently hold it down.Update from Paul Krill at SunNetwork: Sun Chairman/CEO Scott McNealy acknowledged during a press conference today at SunNetwork that the company is laying off slightly fewer than 1,000 workers. The company, however, still is hiring people in some specialty parts of the organization and the company is undergoing a natural rebalancing, McNealy said. “We’ve got 35,000 employees worldwide,” McNealy said.
