WOODBURY - The jobs report released today shows the U.S. unemployment rate dropped to 7.8 percent last month, falling below 8 percent for the first time in nearly four years. While 12 million Americans are still out of work, that's the fewest since January 2009. Vincent Caretto, of Nesconset, is among the recently employed. He found a niche job five months ago in the green sector after struggling to find a job for more than two years. Carretto found his job through Education and Assistance Corporation, a program which offers free job skills training, among other services. Now, Carretto is helping others in the same boat, working as a mentor in the program and telling unemployed Long Islanders that there's a light at the end of the tunnel.
