    Tentative Agreement Reached Between BTA and BUSD on Health & Welfare Benefits (Tuesday, September 27, 2022)

    The BTA and BUSD bargaining unit teams are pleased to share that a Tentative Agreement has been reached on Article 8-Health and Welfare Benefits, the sole reopener for 2022-2023.

    After two days of productive discussions, the teams agreed that the District contribution to health and welfare benefits should be increased. The District and BTA acknowledged that the only Kaiser option for unit members was becoming prohibitively expensive. As a result, the District  offered  to add two additional Kaiser Plans with lower premium options. The bargaining teams agreed to add these additional options for this year’s benefits enrollment period beginning November 1, 2022.  

    BTA’s initial proposal was to increase the District contribution to health benefits to cover the entire premium at the following rates: $947 for employee only, $1894 for employee +1 and $2463 for employee + family. The team discussed the fiscal impact of this proposal.

    The District’s initial proposal was to cover the entire 14.95% Kaiser Plan increase for all employees so there would be zero impact on the employee’s net pay. The change in district contributions would have increased to $788 for employee only, $1500 for employee +1 and $1931 for employee + family.

    BTA then proposed $788 for employee only, $1571 for employee + 1 and $2043 for employee + family. 

    BTA and BUSD ultimately agreed to the District’s offer to increase the District contribution of $805 for employee only, $1515 for employee + 1 and $1970 employee + family, which raises the employee only coverage to be more consistent with comparable districts. 

    The Parties also agreed to increase the in lieu amount for unit members who do not take district health benefits from $200 to $400 and to allow unit member retirees with 20 years or more full-time service to access the district health benefits for vision and dental at the retiree’s cost.

    The Parties look forward to meeting in 2023 to reopen the successor Collective Bargaining Agreement.

    Byron Welcomes New Superintendent


    Crystal Castaneda

    On June 23, 2022, The Byron Governing Board voted unanimously to approve the appointment of Mrs. Crystal Castaneda as the new Superintendent of the Byron Union School District.  Mrs. Castaneda has a rich and varied background that makes her an ideal person for this position.  Her strength as an instructional leader has its roots in her early years as a teacher.  She is a national board certified teacher which reflects excellence in the teaching profession.  At this time there are only 112,000 people nationwide who have received that recognition.  It is this perspective that guides her work because she knows what excellence in instruction looks like and is deeply committed to ensuring the conditions that best support learning for All students. 

    Crystal served as a Principal of Las Juntas Elementary School, a small Title1 school in Martinez, for over 7 years.  She rose from the staff to become their leader, which is not an easy task.  This was a good school that she led to higher levels of excellence; ultimately receiving recognition as a Gold Ribbon School. The school was also recognized for their work with G.L.A.D. (Guided Language Acquisition Design) – a strategy based program that supports English Learners and struggling students. 

    Mrs. Castaneda left Martinez to become the Director of Educational Services in Oakley.  During her tenure in Oakley she partnered with CCCOE to obtain a $5 million literacy grant.  She provided district wide MTSS training and provided support for Social and Emotional Learning and the Positive Behavioral Intervention and Support System.  In her role in Oakley she was responsible for state and federal compliance mandates, audits, categorical programs and ensuring the alignment of the district programs in the LCAP to the district budget.  She wore many hats in Oakley which will serve her well in her new position in Byron.

    Most recently Crystal served as the Superintendent/Principal in a small rural school district in Contra Costa County called Canyon.  It was there that she learned the many facets of running a district with very limited resources and personnel.  She is a dedicated, visionary leader who values building positive relationships.  She strives for excellence in her work and has been recognized as the Educator of the Year well as the G.L.A.D. Administrator of the Year.  Her can do spirit and positive outlook will serve her well as she embarks on her new journey in Byron. 

    Crystal’s family is an integral part of her life.  She and her husband of 23 years, Javier, make their home in Clayton with their three children, Isabella (19) a sophomore at San Diego State University, Diego (15) a sophomore at Clayton Valley Charter and Giovanni (11) a 6th grade student at Diablo View Middle School. 

    Congratulations to Bernadette Geer for being Byron Union School District Teacher of the Year!
