The branch of law to govern the relationships that take place through human labour is labour law. This is the set of legal standards that guarantee the respect of the obligations of the parties to an employment relationship.
The labour law considers work as activity a person does to change the outside world and through which she manages to get the material means or economic assets to survive.
As a social fact, work includes the establishment of relations which are not quite symmetrical. The employer (the one that hires the worker) has a major force against the employee. It is for this reason that the labour law was intended to limit somewhat the freedom of the company to protect the deemed unbalanced relationship.
To do this, the right to work is based the principle of protection, unlike private law, of which the principle is that legal equality. That said, the right to work must apply, in respect of the competition's standards, one that is more favourable to the worker.
Labour relations are governed by a contract of employment law and several additional jurisdictions. However, each area of production has its own rules to govern relations not to violate the Act of contract of employment.
In addition, there are the collective labour agreements that are applied to different professional groups. These agreements, which are agreed between the two parties (employers versus employees) must be must be approved by the State.
