When Everyday Activity Does Not Prove Capacity for Sustained Work
A person may be able to garden briefly, take a carefully paced trip, or pursue a small hobby and still lack the reliability and stamina required for competitive employment. In Zayn v. Unum Life Insurance Company of America, an Oregon federal court applied that principle in reinstating ERISA long-term disability benefits.
Nur Zayn, a CVS employee diagnosed with young-onset Parkinson’s disease, stopped working in 2021. Unum approved her long-term disability claim and continued paying benefits after the plan shifted from a “regular occupation” standard to an “any gainful occupation” standard. Unum later terminated benefits effective November 27, 2024, and upheld the decision on appeal.
The claimant still carried the burden
The parties agreed to de novo review, meaning the court weighed the administrative record without deferring to Unum’s decision. Zayn still had to prove continuing disability. The court emphasized that an insurer is not categorically required to prove medical improvement simply because it previously approved benefits.
Unum had meaningful counterarguments. Routine examinations often showed intact memory, fluent speech, a steady gait, and relatively mild motor findings. Neuropsychological testing showed strong performance in many areas. Unum’s reviewers also cited an astrology website and social media account, travel, gardening, and surveillance showing about ten minutes of outdoor activity during sixteen hours on site.
But the court found that evidence incomplete when placed against the full record. Speech and neuropsychological testing documented slowed processing, divided-attention problems, and cognitive fatigue despite Zayn’s intellectual strengths. Her longtime neurologist and other providers consistently described limits affecting concentration, decision-making, fine motor use, sitting, standing, and reliable attendance. Statements from Zayn, her partner, and a friend explained the pacing, assistance, recovery time, and symptom costs behind seemingly ordinary activities.
The court also identified reliability problems in the insurer’s reviews: two reviewing physicians repeated information from another claim file. It found that limited recreational and online activities were consistent with the medical record and did not demonstrate an ability to sustain gainful employment. The Social Security disability award was relevant supporting evidence, though it did not control the ERISA decision.
What the decision means for claimants
The ruling does not create an automatic preference for treating providers. It shows why longitudinal observations may be especially persuasive when symptoms wax and wane or routine office exams do not measure work pace, persistence, and fatigue. Claimants should document not only what they can do, but how long it takes, what help or breaks are required, and what happens afterward.
The different result in Seven Years of LTD Benefits Did Not End Aetna’s Review also shows why the review standard matters: that court deferred to Aetna and considered more recent medical evidence alongside the absence of updated neuropsychological testing.
The court denied Unum’s motion, granted Zayn’s motion, and reinstated benefits effective November 27, 2024. The parties were directed to address back benefits with interest, attorney fees, and costs before submitting a proposed judgment; the court did not set a final dollar amount.
