Hire of Services or Work
This was the case where one person hired another to perform certain services or do certain work. There were two cases; one where the hirer employed the other to perform services not in respect to a particular thing, such as the services of domestic servants, laborers, clerks, etc., and the other where a person was hired to do work upon a particular thing, such as to repair a coat, make a ring, or carry goods. In such case the agreement was not to supply the hirer with a certain amount of labor, but with the result of labor.
( 1 ) The first class of contracts was called locatio-conductio operarum. The employer was called the conductor operarum and the servant or employee the locator-operarum. The subject-matter of this contract must always consist of services of the inferior sort (opera illiberales) not requiring special skill, and reducible to a money value. The services of a lawyer, physician, teacher, mandatory, and the like, were deemed of too high a sort to be debased by being made the subject-matter of trade. They were (in theory) beyond money valuation.
(2) The second class of locatio-conductio was called loccutio-conductio operis. Here the contract was to do certain work upon or in respect to a particular thing. The employer in this case was called, not the conductor, as in the former case, but the locator, and the person employed was the conductor. The nomenclature of the jurists is here somewhat confused, they having apparently followed the analogy of a letting for use in which the bailor is the locator and the bailee is the conductor (see Hunter, 511). Thus the laundress who washes the clothes, or the carrier who carries the goods or the jeweller who repairs a ring, was the conductor, while the owner was the locator.
It may be noted that the Roman jurists, like our own, experienced some difficulty in distinguishing between a sale and a contract for work. Thus if a goldsmith agreed to make out of his own gold a ring for Titius, and received ten aurei therefor, it was disputed whether this was a contract of sale or of hire. One authority (Cassius) held that it was both a sale of the material and a hiring of the labor. But it was finally determined to be a sale. But if Titus provided the gold or simply agreed to pay for the work, it was a contract of hire (Inst. III, 24, 4).
The workman was bound to do his work with reasonable care and skill, and take good care of the thing entrusted to him. If it was lost, destroyed, or injured, through his negligence or want of skill, he was responsible, but not otherwise. Thus, if a precious stone was sent to a lapidary to be cut or set, and the lapidary broke the stone in doing so, he was liable if the fracture was due to his want of skill, but not if due to a flaw in the stone. So, if one agreed to carry an article for hire, and it was lost or injured, the carrier was liable if the loss was due to his fault, but not otherwise.
(The Roman law did not make the distinction made in English law between a common carrier (liable as insurer) and a private carrier.)
