The California Nurses Association announced it will not strike May 29 after it reached a tentative labor agreement with the University of California Friday night.

The agreement between the two sides resolves the ongoing labor dispute at UC medical centers, which could have seen the use of replacement nurses at various hospitals, including UCSD Medical Center Hillcrest, Thornton Hospital and Student Health Services on campus.

The agreement calls for raises of up to 38 percent for some nurses, according to a statement from CNA. Pay increases under the new agreement will be determined by seniority rather than evaluations by managers. The University of California will still be able to reward job performance through lump-sum bonuses, according to a statement from the university.

The agreement also calls for the two sides to form joint committees at each medical center to work together in creating acceptable staffing ratios. Currently there is legislation at the state level to mandate nurse to patient ratios.

Although the agreement still needs to be ratified by the nurses on June 3 and June 4, CNA formally withdrew its plans for the one-day strike.

The University of California operates medical centers at UCLA, UC Irvine, UC San Francisco and UC Davis.
