Article 4 Federal Labor Law

No person may be prevented from working nor from dedicating himself to the profession, industry or commerce that suits him, provided they are lawful. The exercise of these rights may only be prohibited by resolution of the competent authority when the rights of a third party are attacked or those of society are offended:

I.The rights of a third party are attacked in the cases provided in the laws and in the following:

a)When it is a matter of substituting, or an employee who claims reinstatement in his employment is definitively substituted, without the case having been resolved by the Court.

b)When the right to occupy his same position is denied to an employee who has been separated from his work by reason of illness or force majeure, or with permission, upon presenting himself again to his work; and

II.The rights of society are offended in the cases provided in the laws and in the following:

a)When a strike having been declared in the terms established by this Law, it is a matter of substituting or the strikers are substituted in the work they perform, without the conflict that is the reason for the strike having been resolved, except as provided in article 468.

b)When a strike having been declared in equal terms of lawfulness by the majority of the employees of an enterprise, the minority intends to resume its work or continues working.
