My primary complaint was in the organizational changes made by the non-profit. The amount of funding increased significantly, and while some of it was spent on non-volunteer responders the majority of the funding was spent on new bureaucrats. With the funding, the amount of external organizations we were answerable increased. I was suddenly scolded for behaviors I had been doing for years before. Things like calls taking longer than fifteen minutes (when we had lines open, and I am talking to a person in crisis), or me failing to collect enough demographic information from distressed individuals. I didn't want to adapt, and they were more than happy to pay someone $12/hr that will follow orders more closely.
There were a lot of great things that came from the 988 transition. For one, cell phone calls are now routed based on the location of the cell phone, where previous they were routed by the area code of the cellphone number. Another thing, is it did lead to increased call volume. I bet the combination of increased calls, with all calls routing to centers familiar with local resources, drastically increased the amount of detentions coming from suicide hotlines.
