Gov. Jerry Brown barred public schools from using the Redskins name, strengthened the state’s vaccine rules by requiring mandatory vaccination for day care workers and handed a win to the business community by vetoing two bills on the Chamber of Commerce list of so-called “job killers” as he took action on dozens of pieces of legislation Sunday. Brown rejected lawmakers’ efforts to expand the state’s unpaid family leave policy, vetoing legislation by Sen. Hannah-Beth Jackson, D-Santa Barbara, that would have expanded the pool of workers who can take up to 12 weeks off to care for grandparents, grandchildren, siblings and parents-in-law.
