Equipping Your Club or Studio

Q:My director knows our studio microphone is broken and agrees we need to fix it right away. She says she has requested a repair. Yet 3 weeks have elapsed, and nothing
has been resolved. Meanwhile, my voice
is shot. If I refuse to teach until the mike is repaired, I will be considered a problem instructor. But if I continue to teach without a mike, my voice will suffer even more. What should I do?
