Three members of the Southwest Michigan Symphony Orchestra have chosen to resign rather than go through work to make improvements as the result of getting musical warning termination letters. Susan Dietrich-Reed and her husband Steven are two of them, and she says all five who received the letters over the age of 65. Symphony director Sue Kellogg tells WSJM News it is part of contract negotiations and the five receiving the letters were musicians that the music director felt needed some improvements. Dietrich-Reed is questioning if it’s age discrimination, which Kellogg denies. Kellogg was adamant in talks with both WSJM News and MoodyOnTheMarket.com that no musicians have been or are being fired. Dietrich-Reid tells us a sixth musician who is 63 received a “milder disciplinary letter.” She has been playing for 44 years, while her husband has been playing for 40.
