Two agencies within the U.S. Department of Labor enforce parts of the ADA. The Office of Federal Contract Compliance Programs (OFCCP) has coordinating authority under the employment-related provisions of the ADA. The Civil Rights Center (CRC) is responsible for enforcing Title II of the ADA as it applies to the labor- and workforce-related practices of state and local governments and other public entities. Visit the Laws & Regulations subtopic for specific information on these provisions.

Many people with disabilities use assistive technology that enables them to use computers. Some assistive technology involves separate computer programs or devices, such as screen readers, text enlargement software, and computer programs that enable people to control the computer with their voice. Other assistive technology is built into computer operating systems. For example, basic accessibility features in computer operating systems enable some people with low vision to see computer displays by simply adjusting color schemes, contrast settings, and font sizes. Operating systems enable people with limited manual dexterity to move the mouse pointer using key strokes instead of a standard mouse. Many other types of assistive technology are available, and more are still being developed.

An employer generally does not have to provide a reasonable accommodation unless an individual with a disability has asked for one. if an employer believes that a medical condition is causing a performance or conduct problem, it may ask the employee how to solve the problem and if the employee needs a reasonable accommodation. Once a reasonable accommodation is requested, the employer and the individual should discuss the individual's needs and identify the appropriate reasonable accommodation. Where more than one accommodation would work, the employer may choose the one that is less costly or that is easier to provide. 

2.1 is about enhancing and optimizing your accessibility. If your website only complies with 2.0, it doesn’t mean it’s inaccessible. Most companies are completely caught off guard by accounting for access to disabled – this is what’s being litigated across the US right now – so you’re by no means behind if you haven’t integrated all of the new updates.
The idea of federal legislation enhancing and extending civil rights legislation to millions of Americans with disabilities gained bipartisan support in late 1988 and early 1989. In early 1989 both Congress and the newly-inaugurated Bush White House worked separately, then jointly, to write legislation capable of expanding civil rights without imposing undue harm or costs on those already in compliance with existing rules and laws.[27]
Because they only read text, screen readers and refreshable Braille displays cannot interpret photographs, charts, color-coded information, or other graphic elements on a webpage. For this reason, a photograph of a mayor on a city’s website is inaccessible to people who use these assistive technologies, and a blind person visiting the website would be unable to tell if the image is a photo, a logo, a map, a chart, artwork, a link to another page, or even a blank page.

The ADA has been criticized on the grounds that it decreases the employment rate for people with disabilities[48] and raises the cost of doing business for employers, in large part due to the additional legal risks, which employers avoid by quietly avoiding hiring people with disabilities. Some researchers believe that the law has been ineffectual.[49] Between 1991 (after the enactment of the ADA) and 1995, the employment rate of men with disabilities dropped by 7.8% regardless of age, educational level, or type of disability, with the most affected being young, less-educated and mentally disabled men.[50] Despite the many criticisms, a causal link between the ADA and declining disabled employment over much of the 1990s has not been definitively identified.[51]

Small businesses with either $1,000,000 or less in revenue or 30 or fewer full-time employees may take a tax credit of up to $5,000 annually for the cost of providing reasonable accommodations such as sign language interpreters, readers, materials in alternative format (such as Braille or large print), the purchase of adaptive equipment, the modification of existing equipment, or the removal of architectural barriers.
