Repetitive stress injuries often don’t have a single “day it happened.” Instead, they develop through sustained strain—gripping, typing, scanning, lifting, or maintaining posture for long stretches.
In practice, that means defense teams commonly argue one of these points:
- Your symptoms began before the job period you claim.
- The work wasn’t the real cause (they suggest pre-existing conditions or off-duty activities).
- You didn’t report problems promptly, so the timeline looks weak.
- Medical records are too general, without tying restrictions to work demands.
Washington workers frequently face additional pressure: shift schedules, production expectations, and “push through it” culture can delay treatment and documentation. That delay can become the insurer’s main talking point.
