  • Some employers must post the Missouri Workers' Compensation Poster in the workplace, depending on the size of the workforce and the industry in which the employer operates. See Notice Requirements.
  • Most employers must carry workers' compensation insurance or be self-insured, with two notable exceptions. See Covered Employers.
  • All employers, whether full-time or part-time, are covered, with few exceptions. See Covered Employees.
  • All injuries or illnesses arising out of and in the course of employment are covered by workers' compensation insurance. See Compensable Injuries and Illnesses.
  • Employers may not be liable for all injuries incurred under specific circumstances. See Employer Defenses to Workers' Compensation Claims.
  • Workers' compensation insurance pays for all medical costs as well as partial payment of wages due to lost time and other benefits. See Benefits.
  • All claims must be made within two years of the date of the accident or the last payment of benefits. See Claims Procedure.
  • Employers are prohibited from retaliating against employees who file or pursue workers' compensation claims or who participate in workers' compensation-related investigations. The Missouri Supreme Court has also articulated a specific standard by which employees must bring workers' compensation retaliation claims. See Retaliation and Discrimination.
