This just in: Lawsuit Seeks Overtime Pay for Epic Technical Writers
There are two new lawsuits suing Epic for overtime wages, pretty much identical except for which writers each lawsuit affects. The one lawsuit is for writers who left Epic before April 2, 2014 (when an arbitration agreement went into Epic's employment contract); the other is for writers still employed after April 2.
The article didn't say which law firm was involved, but some high-end detective work (I googled James Jansen lawyer) showed that it's Habush, Habush, and Rottier. If you're a current or past writer, you ought to contact them.
