Employed, employed by the employer, or employment relationship

Employed, employed by the employer, or employment relationship means the employment relationship as determined under the common law, under which the key determinant is the putative employer's right to control the means and manner in which the work is performed. Under the common law, "no shorthand formula or magic phrase * * * can be applied to find the answer * * *. [A]ll of the incidents of the relationship must be assessed and weighed with no one factor being decisive." NLRB v. United Ins. Co. of America, 390 U.S. 254, 258 (1968).
