Washington Post National Reporter Greg Jaffe won the January Sidney award for “The worker revolt comes to a Dollar General in Connecticut,” a deeply reported piece that chronicles a struggle for job security and respect at an outpost of the discount retailer.

As described in the announcement by Sidney judge Lindsay Beyerstein, “This story shows the lengths that companies like Dollar General go to keep their employees from organizing.”

The Sidney is a monthly award administered by the Sidney Hillman Foundation that recognizes outstanding investigative journalism.
