W. Harold Asmus (claimant), a teacher in the Waterloo Community School District for twenty-six years, appeals from a decision on judicial review upholding the workers’ compensation commissioner’s denial of his disability claim based on an alleged mental injury. Claimant contends that he is disabled from a severe state of depression caused by the stresses that arose from an alleged tyrannical working environment at his school. The workers’ compensation commissioner found that claimant had established the medical causation elements of a work-engendered mental disability claim, but had not proven the necessary elements to establish legal causation. The district court agreed.
Claimant asserts that the commissioner erred in failing to find that he had established both medical causation and legal causation sufficient to sustain a claim of work-related mental disability. In the alternative, he argues that, if legal causation does not exist, the standards for establishing that condition work a denial of equal protection of the law. After reviewing the record and considering the arguments presented, we affirm the judgment of the district court.
Claimant was a teacher in the Waterloo Community School District from 1975 until April 2000. Except for the first fivе years of this period, he was a sixth grade teacher at Hoover Middle School, primarily teaching science. Claimant was an active member of the teachers’ union and, until shortly prior to resigning as a teacher, was the union representative for his school building. The principal at Hoover Middle Sсhool from 1992 to 1998 evaluated claimant as a satisfactory teacher, although numerous parent complaints about his teaching methods were noted and certain reviews identified poor organizational skills and inability to control his temper.
In the fall of 1998, a new principal began working at Hoover Middle School. Claimant professes to have had no problems in his dealings with that principal during her first year at the school. During the 1999-2000 school year, claimant was diagnosed as suffering from tuberculosis. He alleges that during this school year numerous conflicts with the principal arose that pro
The sources of the stress that claimant identifies as the cause of his depression were the following:
1. The circulation among teachers in the building of a summary of parent input at a recent parent/teacher conference identifying сlaimant by name as having intimidated students. Evidence was produced at the arbitration hearing that these parent complaints against claimant were in fact lodged at the parent/teacher conference. However, the principal agreed that it was a mistake to have circulated a summary that identified the teacher against whom complaints had been made.
2. The principal’s refusal to recommend that certain teachers in the building grade less leniently and more in keeping with claimant’s philosophy of grading. Evidence presented indicated that, in declining to support claimant’s effоrts to change the grading philosophy of other teachers, the principal fully supported his right to apply his own grading philosophy to his students.
3. Claimant’s science classroom, which was one of the largest classrooms in the building, was divided into two rooms. One of the rooms was devoted to the teaching of a remedial English course. Claimant asserted that he needed the larger room to properly teach his science classes. Evidence was offered that the decision to divide the room was made by the central school administration in order to accommodate a much needed remedial English рrogram. Claimant’s classroom was chosen because of its size and the fact it had two doors, thereby facilitating the division.
4. Claimant contends that the building principal altered a district-wide school improvement plan in order to eliminate a seventh grade teacher that the principal did not like. Substantial evidence was offered to show that the school improvement plan had been developed prior to the principal in question arriving at Hoover Middle School and was a decision of central school administration based upon input from the various school buildings in the district.
5. An issue arose regarding an alleged willful circumvention of claimant in the process of teacher’s applications for special training. Substantial evidence was presented that, although claimant, during the time that he was union representative for the building, was required to approve such applications as to fоrm, the applicants who were alleged to have circumvented his review did this after claimant had been replaced as union representative. The dispute arose during a transition period, and the affected teachers indicated they much preferred to go to the new union representative because claimant unduly cross-examined them concerning their effort to secure special training.
6. An alleged pervasive atmosphere of favoritism of some teachers and intimidation of others (including claimant) engendered by the dictates of the building principal.
In 1990 claimant had sought the help of a psychiatrist and was diagnosed as acutely depressed. He was treated regularly for three years during which he was taking the drug Prozac. His psychiatrist indicated that at the end of the three-year period claimant’s depression was in remission. When claimant’s problems with the criminal law arose in April 2000 as a result of his insulting email to the principal and others, he resumed seeing this рsychiatrist. That doctor testified at the arbitration hearing that claimant was suffering from a recurring major depression and posttraumatic stress disorder from child abuse he had suffered at the hands of his stepfather.
This witness testified that claimant equated the principal with his abusive stepfather and that the stresses thus prоduced were a major cause of his current depressive state. In the witness’s opinion, claimant will never be able to teach again. A psychiatrist that examined claimant on behalf of the school district did not agree that the workplace conditions were a producing cause of claimаnt’s depression and was of the opinion that, as a result of previously existing mental problems, he misperceived the situations of which he has complained as a vendetta by the building principal.-
In reviewing the evidence presented, the deputy industrial commissioner concluded that, although the medical evidence presented supported a claim of medical causation for purposes of proving a mentally induced injury arising out of the employment, the evidence did not meet the standard of legal causation that a claimant must show in order to prove a compensa-ble mental injury. After аn exhaustive review of the testimony given by all of the witnesses, the deputy concluded that the stressors claimed were not sufficiently greater or unusual compared to stress experienced by other individuals in like or similar jobs, including those in the Waterloo Community School District, to satisfy the requirements for legal causаtion.
In reviewing the deputy’s decision, the workers’ compensation commissioner adopted the deputy’s findings and conclusions and further noted that the claimant’s allegations of stress, whether because of the specific circumstances alleged or due to the general climate within the school, wоuld not be entirely unusual in a teaching setting. The commissioner ruled that “[t]he claimant’s evidence in this case was not strong enough to cross the line” into levels of unusual stress required for proof of legal causation.
I. The Legal Causation Issue.
In
Dunlavey v. Economy Fire & Casualty Co.,
In reaching their respective decisions in the present case, both the deputy workеrs’ compensation commissioner and the commissioner strictly adhered to the Dunlavey standard of legal causation. They evaluated all of the specific instances that claimant asserts caused him abnormal levels of stress and concluded that events of the same or similar nature would not be abnormаl in the teaching profession. With respect to the generalized claim of a pervasive atmosphere of intimidation testified to by many witnesses, the commissioner noted that this climate, which was attributed to the building principal, would not be an unusual perception in the workplace.
Although the standard of lеgal causation involves an issue of law,
see Dunlavey,
Evidence is substantial for purposes of reviewing the decision of an administrative agency when a reasonable person could accept it as adequate to reach the same finding.
Second Injury Fund of Iowa v. Bergeson,
In applying thesе principles to the present case, we conclude that, while evidence presented by the claimant would permit a finding of legal causation, it does not compel such finding. The ultimate decision in such instances is entrusted to the agency. Consequently, the decision of the workers’ compensatiоn commissioner and the district court must be affirmed. 2
Claimant contends that the legal requirements for establishing a mental injury serve to deny a claimant equal protection of the law under the state and federal constitutions because an additional burden is placed on mental injury claimants that does not exist in еstablishing compensable physical injury. This assertion is premised on the fact that ordinarily it is not required as a condition of compensability that workplace hazards must be of a specified magnitude in order to produce a com-pensable injury,
see Floyd v. Quaker Oats,
We have recognized that, under both federal and state embodiments of equal protection when social or economic legislation is at issue, the states have wide latitude and such legislation will be presumed to be valid if thе classification drawn is rationally related to legitimate state interests.
Sanchez v. State,
In searching for a rational governmental purpose supporting the
Dunlavey
standard of legal causation in mental injury cases, we need only examine thе reasons set forth in that opinion for adopting the standard that was chosen. After considering several different standards of causation in mental injury cases, some more restrictive than the one chosen and some less restrictive, we opted for the standard that was approved because we fеared that if only causation in fact was required this would convert the workers’ compensation system into general mental health insurance because few workers with nontrau-matic mental problems could not show that job stress somehow contributed to that condition.
Dunlavey,
AFFIRMED.
