As you know, the Alliance of Health Care Unions (AHCU) reached a tentative agreement with Kaiser, which USW Local 7600 overwhelmingly voted to ratify in early October. A provision of that union-negotiated agreement included a 3% wage increase to be implemented on October 1, 2018.
The AHCU is made up of more than 20 locals across the United States. All of which have their own bylaws for how contract ratification happens. Unfortunately, that means some members of the Alliance have not completed the ratification process yet.
