The famous non-profit organization is suffering at the (stage)hands of LocalOne.
See below for a couple of takes on the situation.
"Accepting Local 1's demand, Carnegie said in a statement, would 'divert significant funds away from the hall’s music education programs and into stagehand fees.'"
"This is a fight Carnegie Hall needs to win. If the union is allowed to extend its reach to areas outside its purview, then sooner or later every other performing arts institution nationwide will face the same challenge. And they, and their audiences, will pay dearly."
