AB 2716 is the California bill that would mandate paid sick leave for ALL employers (even small ones), albeit with a few exceptions stated in the bill. The bill is modeled after San Francisco's paid sick leave ordinance, here. This is the probably the bill that would have the most impact on employers if it is passed and signed.
But, according to the Legislature's website, the bill has been placed in the Senate Appropriations Committee's "suspense" file (here). So, this bill may be dead, at least for this session.
