An estimated 31,000 registered nurses and other front-line Kaiser Permanente health care workers will return to work on Tuesday after a four-week strike in California and Hawaii to demand better wages and staffing. The union said in a statement Monday that "significant movement at the bargaining table" prompted an end to the walkout. There are no details about what progress was made during negotiations or what a potential deal might look like. Kaiser Permanente officials didn't immediately comment on the union's announcement.

San Francisco teachers who have been on strike over wages and family health benefits have reached a tentative agreement with the school district. The San Francisco Unified School District says schools will reopen to staff Friday and to students Wednesday. District officials planned a news conference later Friday to share details on the agreement. The strike by about 6,000 public schoolteachers started Monday, marking the city's first such walkout in nearly 50 years. The district had closed all 120 of its schools and offered independent study to some of its 50,000 students. Teachers were demanding higher wages, more health benefits, and more resources for students with special needs.
