Forums For Adjudicating Employment Disputes

Certain claims may be asserted before the Missouri Department of Labor and Industrial Relations, the Missouri Commission on Human Rights, and in some instances, local agencies. Most claims may be asserted in courts of general jurisdiction, although certain claims must first be presented to the appropriate administrative agency.


The Main Sources Of Employment Law

Common law, state statutes and state regulations are the main sources of employment law in Missouri. Major state employment statutes include the Missouri Human Rights Act (Mo. Rev. Stat. §§213.010 et seq.), the Missouri Minimum Wage Law (Mo. Rev. Stat. §§290.500 et seq.) and the Missouri Workers’ Compensation Law (Mo. Rev. Stat. §§287.010 et seq.) Individual contracts (whether written or oral) and collective bargaining agreements may also govern the employment relationship.


National Law And Employees Working For Foreign Companies

State law applies to all individuals physically working in the state. Federal law and, in some instances, a national treaty with a foreign government may also apply. The parties may contractually agree to apply a different state’s law in some circumstances.


National Law And Employees Of National Companies Working In Another Jurisdiction

State law applies only when the employee is physically working in the state or when both parties have agreed in writing to the application of Missouri law.


Data privacy

State and federal statutes and regulations related to data privacy are applicable to Missouri employers and employees. Missouri data privacy statutes address such issues as notifications regarding data security breaches (Mo. Rev. Stat. § 407.1500(2)(1)) and the restricted use of social security numbers as employee numbers for any type of employment-related activity (Mo. Rev. Stat. § 407.1355).

Rev. Stat. §§290.400 to 290.450). Variation of rates of pay for male and female employees engaged in the same classification of work are only permitted if based upon a difference in seniority, length of service, ability, skill, difference in duties or services performed, difference in the shift or time of day worked, hours of work, or restrictions or prohibitions on lifting or moving objects in excess of specified weight, or other reasonable differentiation, or factors other than sex, when exercised in good faith(Mo.

Unless an employment contract with a specific term applies, the employment relationship is at-will and may be terminated at any time. An employment contract or collective bargaining agreement may specify termination procedures.

Restricting Future Activities

Contracts in restraint of trade are unlawful in Missouri, and restrictive covenants limiting individuals in the exercise or pursuit of their occupations are in restraint of trade. However, reasonable non-competition and non-solicitation agreements are permitted between employers and employees in order to protect (1) confidential or trade secret business information; or (2) customer or supplier relationships, good will, or loyalty. The agreement must be reasonable in both duration and geographic scope and must be supported by consideration (at-will employment constitutes sufficient consideration under Missouri law). Enforceability of restrictive covenants is determined on a case-by-case basis. Agreements that prohibit an employee (other than a secretarial or clerical employee) from soliciting employees of a former employer are presumed enforceable where they do not exceed 1 year in duration (Mo. Rev. Stat. §431.202). Such agreements with a term greater than 1 year lose that presumption. Agreements that prohibit disclosure of confidential information are generally enforceable. In Missouri, if a court finds that an agreement is too broad, the court has the power to modify the agreement to the extent necessary to make it reasonable.


Whistleblower Laws

Missouri’s Whistleblower Protection Act (Mo. Rev. Stat. §285.575) provides that it is an unlawful employment practice for an employer to discharge an individual protected under the Act. The Act defines “protected person” to be “an employee of an employer who has reported to the proper authorities an unlawful act of his or her employer; an employee of an employer who reports to his or her employer serious misconduct of the employer that violates a clear mandate of public policy as articulated in a constitutional provision, statute, or regulation promulgated under statute; or an employee of an employer who has refused to carry out a directive issued by his or her employer that if completed would be a violation of the law.” Certain exceptions, including supervisory, managerial, or executive employees, will apply to the qualification of a protected person.
