The distinction between independent contractor and employee is an important one in the United States, as the costs for business owners to maintain employees are significantly higher than the costs associated with hiring independent contractors, due to federal and state requirements for employers to pay FICA (Social Security and Medicare taxes) and unemployment taxes on received income for employees. Likewise, employees are protected from being fired without cause, and if fired or let go for other reasons are entitled to unemployment benefits, whereas independent contractors have neither protection nor entitlement. Employees are also entitled to receive overtime pay for work performed over the 40-hour-per-week standard, whereas independent contractors may work any number of hours (including far above this standard) with no change in pay.
