Mahlon Pitney, Coppage v. Kansas — Opinion of the Court
“ Approaching the matter from a somewhat different standpoint, is the employee's right to be free to join a labor union any more sacred, or more securely founded upon the Constitution, than his right to work for whom he will, or to be idle if he will? And does not the ordinary contract of employment include an insistence by the employer that the employee shall agree, as a condition of the employment, that he will not be idle and will not work for whom he pleases, but will serve his present employer, and him only, so long as the relation between them shall continue? ”
