Registered nurses at Alta Bates Summit facilities in Berkeley and Oakland will join colleagues at other Sutter Health facilities for a two-day walkout next week, their union announced.
The California Nurses Association (CNA) served notice on the hospitals Friday.
The action will begin on the morning of Thursday, Dec. 13, according to union spokesperson Charles Idelson.
CNA members staged an earlier two-day job action Oct. 10-11 which resulted in the chain locking out strikers for five days, the period for which it had hired replacements.
While Sutter is a chain with more than 20 hospitals, labor compacts are negotiated between the union and each hospital or hospital group.
No talks are currently scheduled at the Berkeley and Oakland facilities, according to the union.
The chain operates two hospitals in Berkeley, the Alta Bates campus at 2450 Ashby Ave. and the Herrick Campus at 2001 Dwight Way, and the three facilities at its Summit Campus in Oakland: the Merritt Pavilion at 350 Hawthorne Ave., the Providence Pavilion at 3100 Summitt St., and the Peralta Pavilion at 450 30th St.
