As collaboration champions urge enterprises to give employees more social platforms for interaction, the city of Dallas discovered that a few dozen of its workers were spending too much time on social networks already. CNET's Chris Matyszczyk passes along the news that Dallas has reprimanded 50 employees for idling away work hours on Facebook.

The assistant director of the Dallas water department reportedly was among those caught in the net. Over the course of three months, he had his Facebook page open for 68 hours. His defense is that he tended to open it upon arriving at work and leave it open all day but wasn't actually active on the network all that time--which is certainly plausible.

The city's manager, Mary Suhm, said that employees are not permitted to conduct personal business while on the clock. Officials are now developing new social media usage guidelines for city workers.
