It's always hard to predict what the next big thing is in outsourcing, but it's pretty obvious that HR is going to be pretty active in 2013. Aside from the fact that this has been a very active area in the past, Health care was one of the top issues during the Presidential election. It's one of the top issues for the "Fiscal Cliff" talks. So you can pretty much bet it's going to be one of the top issues for next year.
You can expect to put a lot more time figuring out what the new regulations mean, comparisons of competing insurance plans to find the best match for your firm's needs, and the need to answer many questions from your employees on how the new laws affect their benefits. You are going to need more resources to carry on day to day work and still address program changes and new government requirements.
Which means that you're going to have to do a lot of explaining to your staff about how they are going to transition from their old benefits plan to their new one. Will you hire new staff? Or maybe you should engage a Cloud service to get your message across? You could have some videos made to explain changes to your employees, or perhaps one of the Cloud services can directly... with people or automation... answer individual questions about benefits.
Whatever your situation or your preference for handling your situation, just about every HR team is going to have to do more in 2013. The only question is... how are you going to handle the extra work!
