A doing business as name, also known as a trade name and a fictitious business name, is the name under which a business operates that may be different from its original, official name. A company may use DBAs to conduct business under a different name for various reasons. For example, a foreign company may use a DBA in a specific location because its creation name is being used by another business in the same area.
Disability. A food allergy may be considered a disability under federal laws, such as Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act (ADA).
Sometimes headaches are so debilitating that people actually become eligible for SSDI or Social Security Disability Insurance. Social Security does not offer any partial disability coverage, only full coverage for approved disabilities. You are considered disabled if you can no longer perform the tasks you did before, and you cannot transition to other gainful employment. In some cases, headaches are severe enough to put you into this category.
