Cesar Baptista, an assistant director in the water department, had Facebook open for 68 hours during a three-month period. But Baptista said he often opened his Facebook page in the morning and didn't close it while he did other things. He says he no longer opens the site at work.
The Dallas Morning News reports that the inquiry started with a TV station's request.
