At work, that is. "This little item in Reuters Africa is interesting partly because it's about Polish police being ordered not to use a social networking site at work, partly because it was picked up in Africa, and partly because of this sign of the Poland-born site's popularity. Reuters Africa reports that Poland's national police headquarters has banned the social site Nasza-klasa.pl (which means "Our Class" in Polish) from police offices except "for officers trying to track down offenders over the Internet." Reuters picked this news up from the Polish daily paper Dziennik. The report said "an internal investigation had shown police officers were often using Nasza Klasa … for idle chit-chat instead of working." YouTube reportedly has been blocked by "other Polish state agencies" to keep workers focused on work.
