I've spoken with people in the office about this.. they all see it.. I'm confused that no one on this site can see that and the logic in it... That they think auto Login is some evil thing... it makes no sense.
As morganlefay stated, concerning her situation, she knows her children better than you or your ofiice mates. If you cannot see the situation that she is in, and understand how she has taken steps to secure her data, well then, you should start thinking outside of the box you are stuck in.
Maybe when you have children you will handle this differently, fine, but not everyone will do it your way just because you said so.
And if you are really confused by morganlefay using common sense, then I feel sorry for your employer.
