Your on hold messaging does not have to be all about products and services. How about offering medical/health tips – not medical advice – but seasonal things such as using sun screen, inspecting for ticks, symptoms of heat stroke and heat exhaustion, reminders to renew CPR certification and or skills for emergency first aid, symptoms of hyperthermia and hypothermia, the dangers of playing/working on the ice, the health benefits of exercising, eating right, and getting enough rest.
