Employee status is the question of how someone who performs work for an employer is classified. In most cases, they are an employee. However, if certain requirements are met, someone who performs work for an employer may be classified as an independent contractor, in which case the employer has no responsibility for paying employment taxes, or abiding by many other laws that apply to employees. If there is ever any ambiguity or uncertainty as to whether someone is an employee or independent contractor, courts will almost always find an employment relationship. Additionally, in situations where an employer leases employees from another agency, a joint employment relationship may arise, which in and of itself, requires special consideration to avoid confusion.
