This is the key passage:
""Okun's Law," as it came to be known, has been tweaked over the years, and now states that for every two percentage points the economy grows above its long-term trend annually, unemployment falls by a percentage point.
Most economists peg the economy's long-term trend rate at about 2.5%, which is roughly where economists polled by The Wall Street Journal estimate growth stands in the current quarter.That means, according to Okun's Law, that the economy isn't growing fast enough to bring down unemployment."

This was a post from December, 2010. Here are the growth rates in real GDP for the years 2011-2015
Now here are the unemployment rates for the years 2010-2015
So unemployment has fallen quite a bit despite sluggish growth. But the employment picture might not be that great. We see a drop in the unemployment rate of 4.3 percentage points but the increase in the percentage of 25-54 year olds employed was much smaller. Only 2.26 percentage point increase or only about half of the fall in unemployment. Here are the numbers for the percentage of 25-54 year olds employed for the years 2010-2015.
