The expansion includes 67 employees from the Audit Services Department and the Clerk and Recorders Office joining Teamsters Local 455, while 682 staff members from the Department of Transportation and Infrastructure and the Crime Lab have aligned with Local 17. This shift represents a significant change in labor relations for the city, moving from a system of unilateral management to one defined by negotiated contracts.

For workers like Jesus "Chuy" Lopez, a solid waste operator with Local 17, the unionization effort is a response to years of declining workplace conditions. Internal senior auditor Jordon Monk noted that the transition provides staff with the decision-making power necessary to ensure independent oversight, regardless of shifting political leadership. Peter Finn, Director of the Teamsters Public Services and Health Care Division, characterized the development as the culmination of long-term advocacy to secure bargaining rights through a city charter amendment approved by voters last November.
