STOCKHOLM — While investigating computer network trouble, Sweden’s Airport Authority discovered several workers were looking at porn on company time.

As a result, seven employees from the LFV Group were fired while another quit, accusedof violating Swedish anti-child porn laws, reports Sweden's The Local.

The porn surfing prompted the initial investigation, though the airport agency didn't know about workers watching Web porn.

The network was slowing down, which prompted the review of the system. Officials thought it might be a virus, only to discover the porn site traffic was using up a lot of bandwidth.

"I’m both shocked and disappointed," said LFV Group chief, Lars Rekke.

Rekke told the TT news agency, the employees weren't an organized group and in fact worked at different locations around the country.

According to the investigation, the workers spent between 25 to 75 percent of their day surfing for Internet porn.

Swedish labor laws don't call for immediate termination -- it's up to individual companies.  But LFV has a clearly stated policy against visiting any "offensive" website using company computers on company time, and all adult content falls under that rule, part of an agreement each employee must sign.
