The City of San Jose had a sick leave policy that allowed workers who had been with the City for 15 or more years to bank up to 30 weeks of sick time that would be paid out upon retirement. The policy was a unique savings opportunity for City employees that allowed them to earn sick time throughout their careers that would be paid out at their final rate when they left the City.
California state law doesn't require employers to provide paid sick leave to employees. An attempt by New York City to make paid sick leave mandatory there has earned the promise of a veto from current Mayor Michael Bloomberg. It appears that the City of New York will remain on par with the state of California in leaving paid sick time up to the discretion of the employer.
