This may be where many employers will be heading.  Athletic departments at The University of Texas at Austin and Texas Tech University have been using a service to monitor social media of their players.  Texas A&M University also used a service from 2008 until 2012.  The service monitors the social media accounts of the players.  The players are required to agree to such monitoring.  The social media monitored by the service includes Twitter, Facebook, MySpace and YouTube.  See San Antonio Express News report

The schools deny they are acting as big brother.  They insist they are simply trying to protect their players.  One service filters comments for profanity, alcohol, drugs, race and sex.  A proposed state bill would prohibit requiring athletes from being required to this sort of monitoring. 

If this is what the larger universities are doing with student athletes, how long will it be before large employers start doing the same with key employees?
