impairment as substantially, limiting work, the employer must regard an individual as significantly restricted in his ability to perform a class or broad range of jobs.17Hamilton offered no evidence that BELL regarded him to be so limited.
Hamilton presented no summary judgment evidence that workplace attitudes caused his symptoms, an alternate requirement for a finding that an employee is regarded as having an impairment. Hamilton’s tearfulness, overeating, fatigue, and violent outbreak against a co-employee did not occur only as a result of the attitudes of others but were, he admits, symptomatic of PTSD. The anonymous letter submitted to BELL supervisors accusing him of being violent was not the cause of Hamilton’s symptoms.
Also, there is no evidence presented that, although his PTSD did not rise to the level of an ADA disability, BELL treated Hamilton as having a substantially limiting impairment. In sum, we find that the record is without support for Hamilton’s claim that the mental impairments imposed by his PTSD are severe enough or of sufficient duration to constitute a disability under the ADA.
B.
Fürthermore, even if Hamilton were disabled, the ADA requires that BELL’s adverse employment action be taken because of his disability.18 Hamilton was not terminated because of his disability but rather because he violated BELL’s policy on workplace violence.
Several weeks after the rescue, Hamilton, slamming an office door, angrily confronted a physically smaller female manager in front of witnesses after she returned to work from a shopping trip. In response to her appeal to not speak to her in such a tone, he slapped her hand down, yelling that she “get that f — ing finger out of my face.” Additional profanity followed. He stormed from the office'.but then returned to continue his abusive harangue, yelling “You f_ing bitch!” BELL found this behavior to be an egregious violation of its policies, suspended Hamilton at the beginning of February and discharged him at the end of that month.
Although Hamilton argues that the incident was caused by his PTSD, we are persuaded that the ADA does not insulate emotional or violent outbursts blamed on an impairment.19 An employee who is fired because of outbursts at work directed at fellow employees has no ADA claim. BELL had instituted its policy against workplace violence, with provisions for suspension and dismissal for “extremely severe” offenses, before Hamilton’s misconduct. As a BELL employee, Hamilton was held accountable for violating this policy. BELL cited this conduct as its reason for firing Hamilton; we do not regard this reason as pretextual merely because BELL failed to describe the misconduct as workplace violence until the Texas Employment Commission hearing.
The cause of Hamilton’s discharge was not discrimination based on PTSD but was rather his failure to recognize the acceptable limits of behavior in a workplace environment. The nature of the incident, shown by the record, presents a clear case in which Hamilton was fired for his misconduct in the workplace'. We adopt for an ADA claim the well-expressed reasoning applied in the context of a protected activity-retaliatory discharge claim: the rights afforded to the employee are a shield against employer retaliation, not a sword with which one may threaten or curse supervisors.20 Hamilton can not hide behind the ADA and avoid accountability for his actions.
