WETHERSFIELD >> The state's economic picture took on a completely different look Friday with the Connecticut Labor Department's latest employment report.Though the state economy added 900 jobs in January, its unemployment rate increased by one-tenth of a percentage point to 5.5 percent. But even more troubling than that were the Labor Department's revised employment numbers for 2015: Connecticut only added 12,200 jobs last year instead of 26,900 that the state agency had originally reported.
