     It is very possible for a person with a disability to get a job. Depending on the type of disability a

person has, there are many positions available. Of course, he must be realistic in choosing a job. If he has a physical disability, he should look for a job in which he can use his skills and abilities.

     Some larger companies have programs for hiring people with disabilities. It is a good idea to get into

touch with them, as they are much more enthusiastic to hiring people with disabilities due to their positive

past experiences. Some disability-support groups may have lists of companies that have been helpful in the past, have a history of hiring disabled people or know of some working positions that are open to disabled people.

     When talking with an employer about the job, one must be very honest. He should tell the employer

about his disability. It is also important to know whether there are any sorts of' tools or new technology

that could help a person with a disability do a job. For instance, when working with computers, there is

special software that allows one to tell it what to write instead of having to type it. Or a new type of

wheelchair that allows one to do his job easier would also be a very good investment as it may be the key

to getting a job. It is very important for a disabled person to realize that he should not suffer mistreatment

of any kind from the employer. Although his abilities are slightly different from the majority of other

working people, there is no reason for one to he treated badly. He should ask for a fair salary and fair

treatment.
