 For NPR News in the Twin Cities, I'm Emily Ries. Minneapolis Park and Recreation Board commissioners meet later today to hear from the board's negotiators amid an ongoing strike by park workers. A union representing 300 park employees called a strike that started July 4th and ends in a few days. The union and the park board are at odds over the size of wage increases. They also disagree over a move by the board to keep striking workers from returning to their jobs until a new contract is ratified.
