“A contract extension for musicians of the Philadelphia Orchestra expires just after midnight tonight, but players say a strike is not imminent.” That doesn’t mean that a settlement is near, only that the orchestra is scheduled to play children’s concerts this week, and striking against a bunch of kids wouldn’t look too good. Still, there seems to be at least some optimism that a deal could be reached without a work stoppage, especially with the mayor of Philadelphia now taking an aggressive and active role in the process.
