Quan said she and city negotiators met with representatives of International Federation of Professional and Technical Engineers Local 21 and Service Employees International Union Local 1021 on Friday and presented a proposal that included cost-of-living increases.
The unions declined the city's offer to continue talks over the weekend, Quan said.
City facilities, programs and services will be shut down or severely reduced if a strike occurs, Quan said.
Police, fire and emergency services personnel will not participate in a strike and online services will remain available, Quan said.
In addition, the Broadway Shuttle and the East Oakland Sports Center fitness room will remain open and major public works emergencies will still be responded to.
But the list of services that will be unavailable is lengthy, and includes services for children and seniors, libraries, parking enforcement and street sweeping, city restrooms, maintenance, animal control services, police records and permit inspections, among other things.
City negotiators are next scheduled to meet with IFPTE Local 21 representatives on July 5, and might meet with SEIU Local 1021 on Tuesday July 9th.
