Sure, a bunch of sources linked here.

The top google hit for the "myth" is "Debunking a Myth in 1 Chart: Wage & Productivity Growth" [2] from the American Action Forum, a conservative think tank affiliated with a conservative, Republican advocacy group [3]. Basically it claims the original report compared data that aren't comparable. There's also "Why the gap between worker pay and productivity might be a myth" [4] from the American Enterprise Institute, a conservative think tank [5].

I didn't read them closely but part of the methodology in the AEI article used salary and benefits instead of just salary to draw a compensation line closer to productivity. Given that health care is such a huge part of the cost of those benefits, maybe the claim should be that company shareholders are sharing the wealth with workers but that health care costs are so out of control it's eating up all the workers' gains.

EPI response to criticisms, "Understanding the Historic Divergence Between Productivity and a Typical Worker’s Pay" [6].
