6. $4.5 million – Hubbard, et al. v. U.S. Postal Service

Disability discrimination is growing area of litigation risk, and perhaps as a sign of the times this case revolved around the accommodations afforded to deaf and hard-of-hearing workers of the United States Postal Service. The suit alleged that workers with hearing problems were not given provided with technologies and services that would have helped them perform their duties, and that they were frequently subject to scrutiny from other workers at the postal service. The case was settled in July of 2013.
