Disclosure refers to informing a potential or current employer that you have a disability.
According to the Americans with Disabilities Act (ADA), the decision to disclose your disability is a protected right. An employer may not ask you questions that might let them know about your disability before making a job offer. This is also true of people who might be representing you, such as a human service professional.
However, if you have a noticeable disability, an employer can ask you whether you can complete the basic duties of the job you are applying for.
But it is up to you to decide whether to disclose, and when, how much and how.
The decision to disclose can be complicated. The problem is that when someone knows about a disability, it can change the way they see you. They might assume you cannot do a job without even knowing you, because you have a disability.
But, if you need an accommodation, the employer must know that you qualify because you have a disability. So you have to think about what you need, and what discrimination you might face, as a result of your decision.
