Why are employers asking for workers' Facebook passwords?

Why are employers asking for workers' Facebook passwords? Why does anyone care? If people spent as much time on marriage as they do when going through the process of hiring an employee, the divorce rate in the United States would be zero.

First off, I have no sympathy for people who post revealing pictures online, join controversial causes, or write controversial material and sign their name to it, and then get upset when it's used against them in some way. I don't think there's anything wrong with doing it - but why not just mark the pictures as private or friends-only on sites like Facebook, or use an anonymous name when writing a controversial blog? That is, if you're looking for a real job.  If you want to become a well-known pundit like Bill O'Reilly, then by all means publicize your views.  Or if you want attention like entertainers get, then make those pictures available for the world to see.  Just don't expect to get a regular job if you do.

That being said, I have no idea what looking at pictures on someone's Facebook page can tell you about how a potential employee will perform in a job. Will the people who do please come forward and explain this concept to me?  I'm willing to change my opinion, if you tell me what your reasons are, and they make sense.

Am I supposed to believe that the people making hiring decisions are perfect? They've never made mistakes, gotten drunk, or done something stupid or silly? Come on. It makes no difference if you don't have a picture of it - you still did it, so how can you judge someone else? Why not find out what someone can actually do on a job, instead of just guessing as to how they would perform based on their Facebook page?  What if you think their Facebook page is too boring? Does that knock them out as a candidate as well?

Funny how people get all flustered when it comes to hiring a new employee....but then, lots of people just jump into marriage or a relationship. If people spent as much time on relationships or potential relationships as they did when hiring a worker, the divorce rate in this country would be zero.
