The main purpose of this legislation is to improve job opportunities for young adults with disabilities by amending the Rehabilitation Act of 1973. It aims to ensure that these individuals have the freedom to choose their workplaces and are not limited to subminimum wage jobs without proper support and guidance. Key provisions of the law include changes to the rules surrounding the employment of individuals with disabilities. It allows individuals aged 18 and older to choose to accept jobs that may pay less than the minimum wage, but only if they actively make that choice.
