So in the episode Hank passes up a qualified woman for a job and hires a drug addict instead. He finds out and tries to fire him but the ADA prevents him from doing so as he's in rehab. Then other employees feign disability and nothing gets done. Hank eventually quits to reduce the amount of employees so the business doesn't qualify for ADA protections and so they fire the guy.
