Big Brother isn't just watching: workplace surveillance can track your every move | World news | The Guardian

Employee monitoring is an entire industry in itself. I have usually seen this for monitoring website activity to protect companies against security threats and to restrict access to inappropriate content. It’s not a big leap to take that further into general productivity monitoring and even into recommending productivity improvements for people.
