An appellate court recently upheld an earlier court's ruling and determined that the husband of a wife who died when a blood clot developed during her sedentary job is entitled to receive worker's compensation. As of now, experts say this case seems like the first of its kind.

The appellate court case goes back to 2007 when the woman was a manager at AT&T, which is the company she had been with for 25 years. At the time she was working at home, and reportedly was under a tight deadline on a project and ended up sitting at her desk in her home office for more than 10 hours.
