Pittsburgh Symphony musicians have agreed to a new contract with some big concessions. “During the first year of the new contract, which runs through Aug. 31, 2008, musicians will take a 4.2 percent pay reduction, resulting in a savings of $500,000. The orchestra, which posted a $500,000 deficit last year, will reduce the number of musicians from 99 to 95 and institute a hiring freeze. In year two of the contract, an unpaid week of vacation and the hiring freeze will save $1 million. In year three, the PSO will save $900,000.”
