  • Due to a recent new interpretation of Missouri statutes, all new petitions will need to be filed by an attorney, licensed in Missouri. It has been determined that deciding what type of a petition to file or what the make-up of the proposed unit will be are legal questions. Section 484.020 RSMo. requires all entities before the state be represented by counsel. 
  • On March 8, 2019 the Circuit Court in St. Louis issued an order enjoining the Missouri Department of Labor and the Missouri State Board of Mediation from administering and enforcing the changes made to the state's public sector labor organization law as passed by the legislature in HB 1413 (2018).
    The Department is reviewing this order and further updates will be posted as appropriate.

Memo to Parties

What is the State Board of Mediation?

The State Board of Mediation is a quasi-judicial board that administers the Public Sector Labor Law (RSMo. Chapter 105.500 - 105.598), which covers most public sector employees who seek union representation.

The board defines an appropriate bargaining unit of employees based on whether or not they share a community of interest and, if certified, determines majority representation status by conducting a secret ballot election. Jurisdiction includes all counties, cities, school districts, special districts, and departments of state government, with a few exceptions.
