Grievances

Grievances are alleged violations of the contract, or violations of certain longstanding practices, on the part of management. Please contact an officer or labor representative as soon as a concern arises for assistance with filling out and submitting a grievance. The timing and wording used on the form can have a significant impact on the outcome of your grievance.

MNA Members: Update your contact info

If you are already an MNA member, update your contact info here so you can get the latest news from your union. 

Assignment Despite Objection Forms

You should fill out an electronic Assignment Despite Objection (ADO) form anytime you are being assigned work that you feel is unsafe, that violates departmental staffing guidelines, or that potentially violates the nursing Code of Ethics. ADO forms can help protect your license by documenting your objection. They also create a record of staffing problems that MNA can use to change dangerous patterns.
