Shared Governance

We have shared governance at the medical center where I work. We have monthly hour-long shared governance meetings on our unit and then our ideas move up the chain of command to (hopefully) become practice, hence the purpose of shared governance. However, we have chronically low turn out at our monthly meetings and therefore are struggling to get things done. Any ideas on how we could increase the attendance at our meetings? We meet at 1pm on the second Tuesday of the month. We have already tried meeting in the evenings and had even worse attendance then. At our last mandatory staff meeting we had the hospital-wide Shared Governance chair come speak with the staff to explain what Shared Governance is all about and we still had only 5 people at our meeting today. We have a staff of at least 40 nurses and 10 CNAs on our 32 bed Cardiovascular Care Unit who work 7a-7p or 7p-7a either full time, part time, or per diem. Any and all input would be appreciated, we are passionate about the power shared governance gives us as practitioners and want our co-workers to see the difference they can make in the way we practice medicine.
