The tentative agreement includes salary adjustments and the continuation of employee health benefits at current levels, reflecting the District’s ongoing commitment to supporting employees and maintaining competitive compensation and benefits.

The District appreciates the collaborative efforts and professionalism demonstrated by CST leadership throughout this process. Both parties worked to reach an agreement that supports employees represented by CST while continuing to prioritize the needs of students and the District community.

This tentative agreement reflects MDUSD’s continued commitment to attracting and retaining high-quality employees by providing competitive wages and comprehensive benefits. The District recognizes the important contributions CST members make each day in supporting school operations and student success across the District.

Upon ratification by CST membership and approval by the Mt. Diablo Unified School District Board of Education, this tentative agreement will conclude negotiations with CST through the expiration of the agreement on June 30, 2027.

Fantastic teamwork from everyone involved. Thank you for collaborating so seamlessly on this agreement.
