According to Human Resource Management the following is the breakdown for why people call in sick:

35% ARE sick
21% Have family issues
18% Have personal issues
14% Want a mental health day
12% Think they deserve a break

So a third are sick, a little over a third are dealing with issues, and little less than a third are taking a needed vacation day.

According to a study by CareerJournal.com and the Society for Human Resources…

40% of people have had an office romance AND 42% of those people ended up marrying a coworker

My take?  People need to get out more.  Picking a mate out of your dating pool is just a fact of life.  Having a crappy dating pool is simply proof a not having a life.
