The status of labor has been markedly changed since the early days of our country. In general it may be said that the worker has tended to acquire a position of even greater bargaining power relative to the employer (indeed, today there are instances where labor holds the superior position.) Of course certain types of laborers have always possessed an advantageous and strategic bargaining power position, but on the whole the tendency toward greater freedom for labor as a class is not disputable. Evidences of this evolutionary movement in the worker's status toward more freedom of contract may be found in the numerous labor agreements and labor indentures in the Baker Library.
