Article 123. The Congress of the Union, without contravening the following basic principles, shall formulate labor laws which shall apply to:

1. Workers, day laborers, domestic servants, artisans (obreros, jornaleros, empleados domésticos, artesanos) and in a general way to all labor contracts:
1. The maximum duration of work for one day shall be eight hours.
2. The maximum duration of nightwork shall be seven hours. The following are prohibited: unhealthful or dangerous work by women and by minors under sixteen years of age; industrial nightwork by either of these classes; work by women in commercial establishments after ten o'clock at night and work (of any kind) by persons under sixteen after ten o'clock at night.

4. For every six days of work a worker must have at least one day of rest.
5. During the three months prior to childbirth, women shall not perform physical labor that requires excessive material effort. In the month following childbirth they shall necessarily enjoy the benefit of rest and shall receive their full wages and retain their employment and the rights acquired under their labor contract. During the nursing period they shall have two special rest periods each day, of a half hour each, for nursing their infants.
6. The minimum wage to be received by a worker shall be general or according to occupation. The former shall govern in one or more economic zones; the latter shall be applicable to specified branches of industry or commerce or to special occupations, trades, or labor.

The general minimum wage must be sufficient to satisfy the normal material, social, and cultural needs of the head of a family and to provide for the compulsory education of his children. The occupational minimum wage shall be fixed by also taking into consideration the conditions of different industrial and commercial activities

Farm workers shall be entitled to a minimum wage adequate to their needs.

The minimum wage is to be fixed by regional committees, composed of representatives of the workers, employers, and the Government, and will be subject to approval by a national committee, organized in the same manner as the regional committees.

7. Equal wages shall be paid for equal work, regardless of sex or nationality.
8. The minimum wage shall be exempt from attachment, compensation, or deduction.
9. Workers shall be entitled to a participation in the profits of enterprises, regulated in conformity with the following rules:
1. A national committee, composed of representatives of workers, employers, and the Government, shall fix the percentage of profits to be distributed among workers.
2. The national committee shall undertake research and make necessary and appropriate studies in order to become acquainted with the general conditions of the national economy. It shall also take into consideration the need to promote the industrial development of the country, the reasonable return that should be obtained by capital, and the necessary reinvestment of capital.
3. The committee may revise the fixed percentage whenever new studies and research so justify.
4. The law may exempt newly established enterprises from the obligation of sharing profits for a specified and limited number of years for exploration work and other activities so justified by their nature or peculiar conditions.
5. To determine the amount of the profits of each enterprise the basis to be taken is the taxable income according to the provisions of the income tax law. Workers may submit to the appropriate office of the Secretariat of Finance and Public Credit any objections they may deem pertinent, in accordance with procedure indicated in the law.
6. The right of workers to participate in profits does not imply the power to intervene in the direction or administration of an enterprise.
10. Wages must necessarily be paid in money of legal tender and cannot be paid in goods, promissory notes, or any other token intended as a substitute for money.
11. Whenever, due to extraordinary circumstances, the regular working hours of a day must be increased, one hundred percent shall be added to the amount for normal hours of work as remuneration for the overtime. Overtime work may never exceed three hours a day nor three times consecutively. Persons under sixteen years of age and women of any age may not be admitted to this kind of labor.
12. In any agricultural, industrial, or mining enterprise or in any other kind of work, employers shall be obliged to furnish workmen comfortable and hygienic living quarters for which they may collect rent that shall not exceed one half percent monthly of the assessed valuation of the property. They also must establish schools, hospitals, and any other services necessary to the community. If the enterprise is situated within a town and employs more than one hundred workers, it shall be responsible for the first of the above obligations.

In addition, in these same work centers, when the population exceeds 200 inhabitants, a tract of land of not less than five thousand square meters must be reserved for the establishment of public markets, the erection of buildings destined for municipal services, and recreation centers. Establishments for the sale of intoxicating liquors and houses for games of chance are prohibited in all work centers.
14. Employers shall be responsible for labor accidents and for occupational diseases of workers, contracted because of or in the performance of their work or occupation; therefore, employers shall pay the corresponding indemnification whether death or only temporary or permanent incapacity to work has resulted, in accordance with what the law prescribes. This responsibility shall exist even if the employer contracts for the work through an intermediary.
15. An employer shall be required to observe, in the installation of his establishments, the legal regulations on hygiene and health, and to adopt adequate measures for the prevention of accidents in the use of machines, instruments, and materials of labor, as well as to organize the same in such a way as to ensure the greatest possible guarantee for the health and safety of workers as is compatible with the nature of the work, under the penalties established by law in this respect.
16. Both employers and workers shall have the right to organize for the defense of their respective interests, by forming unions, professional associations, etc.

In public services it shall be obligatory for workers to give notice ten days in advance to the Board of Conciliation and Arbitration as to the date agreed upon for the suspension of work. Strikes shall be considered illegal only when the majority of strikers engage in acts of violence against persons or property, or in the event of war, when the workers belong to establishments or services of the Government.

21. If an employer refuses to submit his differences to arbitration or to accept the decision rendered by the Board, the labor contract shall be considered terminated and he shall be obliged to indemnify the worker to the amount of three months' wages and shall incur any liability resulting from the dispute. This provision shall not be applicable in the case of actions covered in the following section. If the refusal is made by workers, the labor contract shall be considered terminated.
22. An employer who dismisses a worker without justifiable cause or because he has entered an association or union, or for having taken part in a lawful strike, shall be required, at the election of the worker, either to fulfill the contract or to indemnify him to the amount of three months' wages. The law shall specify those cases in which the employer may be exempted from the obligation of fulfilling the contract by payment of an indemnity. He shall also have the obligation to indemnify a worker to the amount of three months' wages, if the worker leaves his employment due to lack of honesty on the part of the employer or because of ill treatment from him, either to himself or to his wife, parents, children, or brothers and sisters. An employer may not relieve himself of this responsibility when the ill treatment is attributable to his subordinates or members of his family acting with his consent or tolerance.
23. Credits in favor of workers for wages or salary earned within the last year, and for indemnity compensation, shall have priority over all other obligations in the event of receivership or bankruptcy.
24. A worker alone shall be responsible for debts contracted by himself and payable to his employer, his associates, members of his family, or dependents, and in no case and for no purpose may payment be exacted from members of the worker's family, nor are these debts demandable for an amount exceeding the wages of the worker for one month.
