A: Under the FMLA rule, an employer must provide leave under whichever statutory provision provides the greater rights to employees.34 For examples of how this principle is applied, see the FMLA rule at  825.702(b)-(e).
In addition to federal law, 25 states have supplemented FMLA protections by providing either longer leave (e.g. up to 16 weeks), lowering the minimum employer size to below 50, or even requiring private employers to pay for maternity leave (up to some cap).
