Do I have a disability discrimination case?
In 1990, Congress passed The Americans with Disabilities Act, which generally made it illegal for employers to discriminate against employees who have disabilities. If you do have a disability, which is defined as an impairment that affects a major life function, then you have a right to have an accommodation from your employer, as long as that accommodation is reasonable and not overly burdensome to your employer.
If you have an impairment or a disability that requires a special seat, for example, or some other change in the normal work process, your employer may have a legal obligation to give you that accommodation so that you can continue to work. If you have any problems getting the accommodation, then you should consider consulting an employment lawyer, who can help walk you through the situation.
