We’re not taking vacations, at least according to a study by Project.  The Associated Press reports that over the last 15 years Americans are taking less and less vacation time.  More than half of Americans are leaving vacation time on the table.   The story offers tips on why you should take a vacation.

According to the report, 658 million vacation days went unused by Americans last year alone.  More than a third of those days cannot be “rolled over” into another year.  The survey notes many employees don’t want to go on vacation because they fear a high work load, when they return.  Others feel no one else can do their job.
