Workplace Prof Blog has an interesting post here on a case from the U.S. Court of Appeals for the Seventh Circuit affirming the dismissal of an FMLA case on summary judgment because the employee had only worked 1249.8 hours during the preceeding twelve months.  In other words, the plaintiff missed FMLA eligibility by 12 minutes.  From a practical standpoint, this is one good reason to maintain accurate records of employee leave.
