2015 has been a notable year for the passage and implementation of local mandatory paid sick leave (PSL) laws. In addition to statewide laws taking effect in California and Massachusetts, new local laws have taken effect in Emeryville and Oakland, California; Bloomfield, East Orange, Irvington, Montclair, Paterson, and Trenton, New Jersey; and in Philadelphia, Pennsylvania. New laws also have been approved, but will not take effect until 2016, in Montgomery County, Maryland, and Tacoma, Washington. In response to the surge in local leave laws, some state officials have attempted to curb local governments’ authority to enact such measures. New legislation in Michigan, Missouri, and Oregon demonstrate some of the varying approaches legislators have taken to curtail the proliferation of local PSL laws.
