Unreported employment, also known as unlawful employment, illegal employment, working under the table or off the books is employment that is illegal and not reported to the government. The employer or the employee often does so for tax evasion or avoiding and violating other laws such as obtaining unemployment benefits while being employed. The working contract is made without social security costs and does typically not provide health insurance, paid parental leave, paid vacation or pension funds. It is a part of what has been called the underground economy, shadow economy, black market or the non-observed economy.
Payments are generally in cash, and the employer often does not check the employee's background or credentials, as is sometimes required by law or otherwise expected by the industry's client base, such as a license or professional certification.
