There is a trend in the discussion in relation to Obamacare about the shift to part time work. This is just false. The move to part time workers is actually a larger market labor trend that began during the Great Recession. As the chart below highlights you can see a clear spike in the rise of involuntary part time work, that is part time workers who are working part time but wish to work full time.
In fact what the data is actually showing us in this chart is not only Obamacare the cause of the part time worker, as those who oppose Obamacare are falsely pushing on network tv, but the number of involuntary part time workers is actually coming down since it's peak just after the start of The Great Recession.
