One thing rings true when it comes to the Affordable Care Act (ACA): “expect the unexpected.” I know this sounds cliché, but it was my best attempt to describe the experience HR professionals encounter as they attempt to comply with this somewhat murky piece of legislation. Last year on December 28, we were alerted a month from the approaching deadline that the forms and filing requirements had moved two and three months out to address challenges. This was a fairly drastic move within a month of a significant compliance deadline.
