Many states and municipalities’ efforts to update workplace regulations governing paid leave beyond the federal Family and Medical Leave Act are presenting difficulties for employers, particularly large ones that operate in numerous states, labor and employment experts said.

At least 7 states and D.C. have introduced legislation recently that offers or expands paid family or medical leave: California, New Jersey, New York and Rhode Island currently require paid family leave, which is funded through employee payroll deductions and existing temporary disability insurance programs.
