Section 287.420 provides, in pertinent part:
> 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 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.
Employee had a preexisting history of on-the-job injuries with this employer. Furthermore, employee's job responsibilities for employer specifically included reporting

and documentation of on-the job injuries involving workers he supervised. Considering these undisputed facts, employee's failure to provide proper notice to employer of the time, place and nature of his injury within thirty days after the accident, as required by § 287.420 is not reasonable or understandable. Employee's failure to provide written notice within thirty days of his alleged April 6, 2013, injury to employer further supports the conclusion that no specific work-related accident occurred that day.
**Medical Causation and Disability**
**I. Disability attributable to lower back**
The opinion of employee's expert Dr. Brent Koprivica that employee sustained disability due to a work injury on April 6, 2013, is unsupported by contemporaneous medical records and conflicts with employee's earlier medical records describing chronic lower back complaints beginning in 2011.
The fact that employee's clinical examination was positive at every level for symptom magnification is undisputed. Dr. Koprivica conceded that employee's reported complaints were an invalid indicator of his physical capabilities. Employee tested positive on Waddell's testing, consistent with malingering or attempting to mislead an examining physician as to the extent of disability. Dr. Koprivica further found that employee's efforts during his examination were submaximal and that, during the course of his examination, employee demonstrated an ability to perform physical movements he earlier denied.
On cross-examination, Dr. Koprivica's admitted that employee's chronic lower back pain prior to the alleged work injury was likely to have been disabling and that, if so, this preexisting condition would have been included in his 15% evaluation of disability related to employee's alleged April 6, 2013, work injury. When a medical condition results from one of two causes, only one of which would be employer's responsibility, the burden of proof has not been met. *Griggs v. AB Chance*, 503 S.W.2d 697 (Mo. App. 1973).
**II. Psychological Disability**
The majority bases its finding that employee sustained 5% permanent partial disability to the body as a whole due to the psychological impact of his alleged April 6, 2013, work injury exclusively on psychologist Dr. James Jackson's expert opinion. Dr. Jackson's objectivity is suspect because Dr. Koprivica considers Dr. Jackson to be his employee. Dr. Jackson conceded approximately 40% to 50% of his practice involves referrals from either Dr. Koprivica or attorneys who have consulted Dr. Koprivica.
In estimating employee's work-related psychological disability, Dr. Jackson assessed 20% of the body as a whole for depression that developed following employee's separation from employment with employer. Dr. Jackson identified a number of "stressors," including loss of income and loss of self-esteem that related to employee's discharge. On cross-examination, Dr. Jackson was unable to specifically identify what portion of employee's depression was attributable to his employment separation.

Furthermore, § 287.120.9 provides, "A mental injury is not considered to arise out of and in the course of an employment if it resulted from any disciplinary action, work evaluation, job transfer, layoff, demotion, termination, or any similar action taken in good faith by the employer (emphasis added)." There is no competent evidence that supports a finding that employee's December 12, 2013, discharge, prompted by complaints of harassment by coworkers, and decided on only after employer imposed progressive discipline, was an action taken in bad faith. Pursuant to § 287.120.9, no compensation should be awarded for employee's alleged work-related psychological disability.
