The Illinois Philharmonic Orchestra, based in Park Forest, announced that it has reached a new three-year collective bargaining agreement with its musicians, effective through the 2024-25 season. Highlights of the agreement include a 12.5 percent pay increase, increased collaboration between musicians and management to expand the variety and availability of small-ensemble concerts, changes to recruitment, audition, and retention procedures to address equity and inclusion at IPO, and updated Covid-19 wellness protocols, aimed at keeping musicians healthy and performances live. Musicians will now be able to accrue a limited amount of sick time, which the orchestra states is a first for per-service orchestras in the region. The orchestra has also announced a four-year contract extension for Music Director Stilian Kirov, through the 2026-27 season. The IPO will mark its 45th anniversary this season; Christina Salerno is the orchestra’s executive director.
