Decision A534P – San Diego Metropolitan Transit System
SA-SV-1-P
Decision Date: December 16, 2025
Decision Type: Administrative Appeal (Non-Precedential)
Description: Petitioner Transit Electromechanics Union (TEU) appealed an administrative decision by the State mediation and Conciliation Service (SMCS). SMCS dismissed TEU’s petition for certification as the bargaining representative of a unit of employees of the San Diego Metropolitan Transit System (MTS). On October 2, 2024 TEU filed a position with SMCS seeking to sever Light Rail Vehicle (LRV) Electromechanics, LRV Linemen, and LRV Assistant Linemen from an already existing bargaining unit pursuant to PERB Regulation 72005(a)(3). The existing bargaining unit is the San Diego Trolley, Inc.’s general bargaining unit, which is represented by the International Association of Sheet Metal, Air, Rail, and Transportation Workers (SMART). On August 14, 2025, SMCS issued an Order to Show Cause why TEU’s petition should not be dismissed. After TEU filed a timely response, SMCS dismissed TEU’s petition. TEU appealed the dismissal on October 24, 2025 and MTS and SMART filed responses to that appeal.
Disposition: In a non-precedential decision, the Board affirmed SMCS’s conclusion that TEU failed to demonstrate that severance of LRV employees is appropriate. The Board denied TEU’s appeal of the October 14, 2025.
