Missouri has no general law regarding family and medical leave but does provide leave for adoptive parents who are public employees. State employees who donate organs are also provided leave. Those provisions can be located in Title VIII, Chapter 105 of the Missouri Revised Statutues. Nursing mothers' rights are provided in Title XII, Chapter 191 of the Missouri Revised Statutues.
