Many of nurses who opposed this proposition were in some level of the management hierarchy. It also seemed like nurses who work in settings that would not have been covered by the proposition were quite bitter about that fact (LTC, nursing homes, etc.) News flash for them, now that won't ever happen. Then there were some nurses who were intimidated by their management and c-suite....scare tactics work, sadly. Naturally, some folks were opposed on political grounds.
I think there are some good arguments against ratios, but those arguments don't outweigh the benefits.
Interestingly, the yes:no ratio almost directly matches the support:opposition expenditure ratio.
