Here is an article that I found through SHRM that talks about how more employers are offering part-time employees health benefits:

Do you think this is a good idea - why/why not? And do you think this is a sustainable practice - why/why not? How do you think the Affordable Care Act now impacts this, or is this a separate consideration..?

Remember - think long-term strategy from the HR perspective when considering this..!

And be sure to use good supporting citations to back up your points.
