Pennsylvania school districts keeping substitute teacher hours under 30 because of Obamacare

This is one of the rules that was supposed to go into effect this last January.  As we get closer to January 1st, more and more people are going to be forced back to less than 30 hours of work a week. As one teacher points out in this news story on WTAJ (CBS TV in Altoona, PA), what happens when the primary teacher is sick for a week?  The students can't even have the same substitute for the same week.
