How do our Bargaining Units work?

The Ontario Nurses’ Association is a union for nurses, by nurses. As an ONA member, you have a say in ONA’s agenda and your representatives.

ONA has strong Bargaining Unit representation and leadership. Individual members belong to an ONA Bargaining Unit. Members elect their Bargaining Unit President, Bargaining Unit committees and unit representatives, Local Coordinator, Secretary and Treasurer. Your elected team works with members to improve your working conditions and maintain your rights under the collective agreement.

Your Bargaining Unit belongs to an ONA Local. The Local Coordinator acts as a resource on governance issues and provides advice to Bargaining Unit Presidents on many items including funding of bargaining unit leave issues. The Local Coordinator also serves as a link between the broader membership and the ONA Board of Directors. Local Coordinators attend ONA provincial meetings and report back to membership on resolutions and/or directions that stem from the discussions.
