By amending sections 558, 1197, and 1197.1 of the California Labor Code, Assembly Bill 970 authorizes the Labor Commissioner to investigate and, at the request of local government, enforce local laws regarding overtime hours or minimum wage provisions. The Labor Commissioner may issue citations and penalties for violations, except when local government has already issued a citation for the same violation. In addition, AB 970 amends section 2802 of the California Labor Code by authorizing the Labor Commissioner to issue citations and penalties to employers for violating the expense reimbursement requirement of section 2802. AB 970 takes effect on January 1, 2016.
