amascuba:The main reason why companies install filters is to help production. The more people are surfing the internet at work the less work they are getting done. After all, you get paid to do a job. My boss has a good way of putting it. His explanation is "We (The company) purchases a block of time from you (the employee) and we want good results of the block of time that we purchase."
Good thing my job is based on network uptime and ensuring that my techs keep desktops and labs running for folks to complete their jobs. 100% uptime on the network for over 365 days now and other than the 30 pc's that lightning smoked back in August, all but 3 of the PC related issues are user instigated (ID10T issues). The other issues are warrantied items. Purchase my block time and thats what you get. In fact, there are things we do that the end user will never see or understand that continue to make our team invaluable... Thats why we're able to negotiate a salary that keeps us on the curve of what CoL is really like here and not 5 years behind.

Bleeding edge industry standards baby!!!
