Section 287.420 RSMo deals with the notice an injured employee must provide to her employer and provides, in pertinent part, as follows:
> No proceedings for compensation for any accident under this chapter shall be maintained unless written notice of the time, place and nature of the injury, and the name and address of the person injured, has been given to the employer no later than thirty days after the accident, unless the employer was not prejudiced by failure to receive the notice.
The purpose of the foregoing section is to give the employer a timely opportunity to investigate the facts surrounding the accident and, if an accident occurred, to provide the employee medical attention in order to minimize the disability. *Soos v. Mallinckrodt Chem. Co.*, 19 S.W.3d 683, 686 (Mo. App. 2000), overruled on other grounds by *Hampton v. Big Boy Steel Erection*, 121 S.W.3d 220, 224 (Mo. banc 2003). The statute sets forth six requirements: (1) written notice, (2) of the time, (3) place, and (4) nature of the injury, and (5) the name and address of the person injured, (6) given to the employer no later than thirty days after the diagnosis of the condition. *Allcorn v. Tap Enters.*, 277 S.W.3d 823, 828 (Mo. App. 2009).
We conclude that employee did not provide employer with a written notice that meets the requirements of § 287.420 RSMo. An incident report exists, but it contains no mention of any injury to employee's neck or right upper extremity, and it was not completed by employee until more than 30 days had passed from the alleged date of accident. Thus, we proceed to the question whether employee demonstrated that employer was not prejudiced by her failure to provide written notice.
The most common way for an employee to establish lack of prejudice is for the employee to show that the employer had actual knowledge of the accident when it occurred. If the employer does not admit actual knowledge, the issue becomes one of fact. If the employee produces substantial evidence that the employer had actual knowledge, the employee thereby makes a prima facie showing of absence of prejudice which shifts the burden of showing prejudice to the employer.
However, when the claimant does not show either written notice or actual knowledge, the burden rests on claimant to supply evidence and obtain the Commission's finding that no prejudice to the employer resulted. If no such evidence is adduced, we presume that the employer was prejudiced by the lack of notice because it was not able to make a timely investigation.

It is well settled that notice of a potentially compensable injury acquired by a supervisory employee is imputed to the employer. Hillenburg v. Lester E. Cox Medical Ctr., 879 S.W.2d 652, 654-55 (Mo. App. 1994). But we have found that employee did not tell a supervisor about her injuries, and that employer did not have actual knowledge that employee claimed to have sustained injuries to her neck and right upper extremity on May 16, 2007.
Employee points to the evidence that it was not uncommon for employer to get halfcompleted incident reports or occasionally even lose completed reports, arguing that nothing out of the ordinary occurred here and thus employee's failure to provide notice should be excused. We are not persuaded. There are a number of reasons why employer might have occasionally received half-completed reports or lost reports. It appears that employee invites us to assume that employer's workers' compensation procedures were administered in a careless or casual fashion, and thus employee should be excused for her failure to complete the report, but we decline to so speculate, and in any event, we fail to see the connection to the question whether employer was prejudiced given the circumstances of this particular case. Apart from her argument that the incomplete report and her interaction with the people at the ACC desk should constitute actual notice, employee fails to identify any other evidence to show employer was not prejudiced, and we can find no other evidence adduced or supplied by employee that so demonstrates. Accordingly, we will presume that employer was prejudiced.
Employee sought treatment and proceeded to surgery on her own. Employer was deprived of the chance to provide immediate treatment in order to minimize the effects of the work injury, and was also deprived of the opportunity to secure a contemporary evaluation of the nature and extent of the injuries employee suffered in the alleged accident. In a case such as this, where accident is at issue and the parties contest whether employee's injuries resulted from degenerative processes or a traumatic event,
