(Portland, OR)  --  New details are coming to light regarding the resignation of the head of HR for Portland Public Schools.  The Oregonian reports Kylie Rogers was under investigation by the school district when she quit last month.  It's not known why she was being put under a microscope, nor is it known if the probe had anything to do with her resignation.  Rogers is reportedly keeping mum about it all.  PPS spokesman Harry Esteve is saying that Rogers left Oregon's biggest school district on her own, citing concerns about work load versus family duties.
