Most companies will have a &quot;reasonable personal use&quot; clause (e.g., shopping Amazon on your lunch break, etc) with regards to company PCs.  I never assumed that they weren&#x27;t logging EVERYTHING, especially once everyone was forced to switch to MS Lync for internal IM.<p>The last BigCo I worked for had a hard-coded login screen on the Windows machines that stated the company use policy in large text and that user activity on company equipment could be monitored at any time and no expectation of privacy was to be assumed.<p>Being in IT, I was told by the security and proxy guys (who I worked closely with) that they only usually had to pull up logs when it was necessary to fire someone - stuff like oilfield workers browsing kiddie porn from drill sites and such.  It happened a lot more than you&#x27;d expect.
