Civil Code, Art. 1711

Owners of enterprises and other employers are obliged to pay compensation for the death of or injuries to their laborers, workmen, mechanics or other employees, even though the event may have been purely accidental or entirely due to a fortuitous cause, if the death or personal injury arose out of and in the course of the employment. The employer is also liable for compensation if the employee contracts any illness or disease caused by such employment or as the result of the nature of the employment. If the mishap was due to the employee's own notorious negligence, or voluntary act, or drunkenness, the employer shall not be liable for compensation. When the employee's lack of due care contributed to his death or injury, the compensation shall be equitably reduced.
