In Missouri, there is a 3-day waiting period.  This means that you have to miss 3 days of work before the workers' compensation carrier must begin paying you.  If you are unable to go back to work within 14 days of the accident, you will be repaid for those first 3 days of missed time.  On the other hand, if you miss less than 14 days of work, you will not be paid for those first 3 days.
