Sick? On MySpace?

Privacy experts, start your engines.  This story just blows my mind.  My brother used to consult a high-end restaurant chain in LA, which I will not name.  One of his friends there told him about how now, when employees (and especially the wait staff) call in sick, the management checks their MySpace pages.  I assume here that employees are required to give their email address upon application and the management looks on MySpace via their email (or perhaps just searching for their name).  So, the next time the employee shows up for work, their boss says, “we noticed that you logged into MySpace when you were sick.  Were you really sick?”  I assume the employees’ jaws drop at this point.  So how sick do you need to be to not check a MySpace page?  And more importantly, aren’t slacker employees going to be slacker employees wherever you find them (offline or online)?  This restaurant chain had problems with micro-managing people, employee turnover, and attracting the wrong kind of wait staff.  Sounds like they need a lesson in how to motivate people!!  So, what are high school teachers and principals doing? Are they checking MySpace or Facebook pages when their students are sick?
