With Barker becoming a restricted free agent in the off-season, the NHL Players Association filed a grievance on July 6, 2009, against the Blackhawks on Barker's behalf for not extending a qualifying offer by the required deadline. As such, the NHLPA argued that Barker (as well as five other Blackhawks players in the same situation) qualified as an unrestricted free agent and could entertain offers from other teams around the league. The Blackhawks quickly came to terms with Barker the same day, re-signing him to a three-year contract worth US$9.25 million.
