William C. ROBERTS
v.
STATE of Louisiana, Through the LOUISIANA HEALTH AND HUMAN RESOURCES ADMINISTRATION.
No. 81-C-0974.
Supreme Court of Louisiana.
September 28, 1981.
*1222 Daniel E. Broussard, Jr., of Broussard, Bolton & Halcomb, Alexandria, for plaintiff-applicant.
Steven R. Giglio, Baton Rouge, for defendant-respondent.
MARCUS, Justice.
William C. Roberts[1] instituted this action against the State of Louisiana, through the Department of Health and Human Resources, to recover damages for personal injuries sustained in an accident in the lobby of the United States Post Office Building in Alexandria, Louisiana. Roberts fell after being bumped into by Michael Burson, the blind operator of the concession stand located in the lobby of said building. He alleged that since Burson was employed by the state and acting within the course and scope of his employment at the time of the accident, the state was vicariously liable. Additionally, plaintiff alleged that the state was negligent in failing to properly train and supervise Burson in the operation of the concession stand. Though charged with negligence, Burson was not made a party to the action.
Following a trial on the merits, the district judge rendered judgment in favor of the state and against plaintiff, dismissing plaintiff's suit at his cost. In his written reasons for judgment, the trial judge stated that, finding no employer-employee relationship between the state and Burson, the state was not vicariously liable. He further found that the state had no duty to provide on site mobility training to the blind operator. The court of appeal affirmed the judgment of the district court, concluding that plaintiff failed to prove that Burson was negligent. The court of appeal did not reach the employment relationship issue.[2] On plaintiff's application, we granted certiorari to review the correctness of that decision.[3]
The facts are generally not in dispute. Michael Burson, who was totally blind, operated the concession stand in the lobby of the post office building. On September 1, 1977, at about 12:45 in the afternoon, he left his concession stand to go to the men's bathroom located on the second floor of said building. As he was walking through the lobby toward the elevator, he bumped into plaintiff causing plaintiff to fall to the floor. Burson was not using a cane at the time of the accident. The plaintiff, an eighty-five-year-old attorney, sustained a fractured hip as a result of the accident.
The State of Louisiana, through the Division of the Blind of the Department of Health and Human Resources (formerly the Department of Public Welfare), has been providing services to the blind since 1928. Programs of services to the blind are presently authorized by La.R.S. 46:331-334.[4]*1223 One of the nine services and programs listed in the Division for the Blind Manual, Chapter VII. Services of the Division for the Blind, is the vending stand and small business enterprises program. The vending stand program has its genesis in the Randolph-Sheppard Act passed by Congress in 1936. This act gave authorization for the establishment of vending stands by blind persons in federal buildings. The act was subsequently broadened to include industrial plants and other private locations. The Division for the Blind has been federally designated as the state licensing agency for the operation of the vending stands in this state since 1955. Approximately eighty percent of the monies expended for the implementation of the program is in the form of federal matching funds. There were some one hundred and fourteen vending stands operated by blind persons in publicly and privately owned buildings in this state at the time of the trial of this matter.
A vending stand is defined in the Division Manual as a small business concession, usually in the lobby of a public building or private location, for the purpose of selling such articles as are agreed upon by the custodian of the building and the Department. The stated objective of the vending stand program is to provide blind individuals with remunerative employment. The Division Manual further states that the program has proved to be "one of the most *1224 effective means of affording a blind person the opportunity to earn his own living."
The procedure for setting up a vending stand is set forth in the Division Manual. Sites are selected and procured by the Department which builds the stand, purchases the equipment and provides the initial stock valued at approximately one thousand dollars. The right, title to and interest in the vending stand equipment and initial stock is vested in the Department.
Operators for vending stands are selected from a pool of applicants who have successfully completed a training program conducted by the Division. A license is issued to the operator for an indefinite period but may be terminated by the Department when the stand is not being operated in accordance with its rules and regulations.[5]
The Department, through its vending stand supervisors, regularly and systematically reviews the operation of the facilities. A supervisor visits the stand monthly and evaluates the general appearance of the operation, methods of merchandising, quality and variety of the stock, inventory estimates and prices being charged. The testimony of Department personnel makes clear that management services are provided to insure that this form of business opportunity remains available for the blind persons of Louisiana. If, in the opinion of the supervisor the stand is being operated in such a manner as to jeopardize either the continuance of the location or the operator's ability to make a living, the blind individual will be counseled regarding necessary modifications. A licensed operator is entitled to a hearing if dissatisfied with any action arising from the operation or administration of the vending stand program.[6]
The blind operator receives all profits generated by the concession. The state does not withhold any taxes from the operators nor does it extend any state benefits to the operators. Once the Department has paid for the initial stock, all transactions regarding merchandise are between the vending stand operator and his chosen supplier. Prices for the items are fixed by the *1225 operator within the prescribed guidelines of the Department. When an operator moves out of a stand, he is required to notify the Department in writing and is obliged to reimburse the Department for any shortage in the inventory below the one thousand dollar inventory initially provided. If the stock in the stand is valued in excess of the initial inventory, the new operator has to pay that amount to the outgoing concessionaire.
The issues presented for our consideration are: (1) whether the state was the employer of Burson, the blind operator of the concession stand, and therefore vicariously liable for his alleged negligent conduct and, if so, whether Burson was negligent, and (2) whether the state committed an independent act of negligence.
La.Civ.Code art. 2320 provides the basis for holding an employer liable for the negligent acts of his employees: "Masters and employers are answerable for damage occasioned by their servants and overseers, in the exercise of the functions in which they are employed." To come within the scope of art. 2320, the plaintiff must show the existence of an employer-employee relationship. In evaluating the sufficiency of such proof, courts have been mindful that, by its nature, vicarious liability mandates strict construction. Blanchard v. Ogima, 253 La. 34, 215 So.2d 902 (1968); Keen v. Pel State Oil Co., Inc., 332 So.2d 286 (La.App. 2d Cir. 1976) (on rehearing), writ denied; Strawder v. Harrall, 251 So.2d 514 (La.App. 1st Cir. 1971).
The definition of an employee is set forth in La.Civ.Code art. 163:
Free servants are in general all free persons who let, hire, or engage their services to another in this state, to be employed therein at any work, commerce or occupation whatever for the benefit of him who has contracted with them, for a certain price or retribution or upon certain conditions.
The single, most important factor to consider in deciding whether the employer-employee relationship exists for the purposes of art. 2320 is the right of the employer to control the work of the employee. Hickman v. Southern Pacific Transportation Company, 262 La. 102, 262 So.2d 385 (1972); Blanchard v. Ogima, supra. In Blanchard, we stated:
It is the right of control of the time and physical activities in the other party and the existence of a close relationship between the parties which determine that one is a servant.
We further stated:
"Servant" must be interpreted as that particular kind of agent who has a very close economic relation to, and is subject to very close control by the principal. A servant is one who offers his personal services for a price. He is an integral part of his employer's business and must submit to the control of his physical conduct as well as of his time.
In the instant case, Burson as an operator of the concession stand, had not engaged his services to the state. Moreover, the benefit of his toil inured to him and not to the state. All profits generated from the stand were income to Burson. The state neither shared in the profits nor did it pay him any form of remuneration. While Burson used the state-owned facility and equipment, he was obliged to reimburse the state for losses sustained with respect to the initial inventory supplied by the state.
Burson operated strictly under a license issued to him by the state. The services of the Department in the ongoing operation of his vending stand were in the form of supervision and business counseling. The license required him to abide by the rules and regulations promulgated by the state and federal agencies but these guidelines are clearly distinguishable from the traditional concepts of control used in defining an employer-employee relationship. As a blind person, Burson was not hired or paid wages to do work for the state. He was licensed and supervised in order to be successfully independent.
In the words of Mr. Guy DeCharry, Burson's supervisor:
[O]ur program is to rehabilitate the blind.... He's not working for us.

*1226 He's working for himself.... [I]t is not that we want to force them to do something, you know, from the agency's standpoint, but just merely from the standpoint of keeping our program going.... He's not an employee. In other words he is an independent person. We are in there to counsel him on any of these subjects but ... we can't tell him what to do.
If aggrieved by any agency action, Burson was entitled to a hearing with numerous due process guarantees. While his license was subject to revocation for violations of the regulations, the state's authority to cancel a license, even in a closely supervised occupation, must not be confused with the employer's right of dismissal.
Accordingly, we conclude that under the general principles of the master-servant doctrine as applied to the relationship between the state and Michael Burson in this case, the state was not the employer of Burson at the time of the accident and therefore is not vicariously liable for his alleged negligent conduct. Finding no employment relationship, we do not reach the issue of whether Burson was negligent.
Plaintiff also urges that we find the state to have been independently negligent for its failure to instruct Burson that he must use a cane when traversing the lobby of the post office building.
La.Civ.Code art. 2315 provides in pertinent part:
Every act whatever of man that causes damage to another obliges him by whose fault it happened to repair it.
La.Civ.Code art. 2316 further directs:
Every person is responsible for the damage he occasions not merely by his act, but by his negligence, his imprudence, or his want of skill.
Under these articles, the elements of a cause of action are fault, causation and damage. Straley v. Calongne Drayage & Storage, Inc., 346 So.2d 171 (La.1977); Pence v. Ketchum, 326 So.2d 831 (La.1976). The existence of a legal duty coupled with a breach of that duty are prerequisites to any determination of fault. Pence v. Ketchum, supra. Whether a legal duty is owed by one party to another depends on the facts and circumstances of the case and the relationship of the parties. In all cases, duty can be stated generally as the obligation to conform to the standard of conduct of a reasonable man under like circumstances. Straley v. Calongne Drayage & Storage, Inc., supra.
In the instant case, the state issues licenses only to those blind applicants who have successfully completed training programs in the operation of vending stands. While the state counsels licensees in the operation of the stands, it cannot be said that the state owes a duty to instruct them in the proper method of mobility outside the vending stands. Accordingly, we find no merit in plaintiff's contention that the state was independently negligent in this case.
