If New York is the city that never sleeps, this guy is the exception.

A security guard charged with protecting the Jacob K. Javits Federal Office Building in Manhattan — part of the Federal Plaza complex that houses both FBI and Homeland Security Department offices — was caught on camera doing something that could cost him his position: sleeping on the job.

The guard was recorded just before 5 a.m. on a recent morning, according to the unnamed man who shot the video.

“I was in disbelief, because there’re so many people out there … a lot of competent people out there who are looking for employment who can’t find employment,” the man told WCBS-TV. “But here it is, you have these guys who do have the jobs, who are not taking the job seriously.”

The man told WCBS that he saw two other guards, in addition to the one he recorded, sleeping on the job at Federal Plaza, and that the situation is frightening, given the high-profile nature of the building.

“People’s lives are at stake here,” the man said. “This is not a job where you can be lackadaisical. You have to take your job serious.”

The sleeping guard is an employee of FJC Security Services, WCBS reported, and the firm was quick to issue a response to the video.

“We take these allegations seriously and have launched an immediate investigation into the matter,” the company said. “The guard has been suspended pending this investigation and will not return to this site.”
