To know which collective labor agreement we belong to, we first need to understand what it is. 

It is an agreement negotiated between employee representatives (unions) and employers, through which the working conditions, rights, and obligations that affect both parties are established. These are fundamental aspects to ensure that the work environment is fair and equitable.

How can you find out which agreement you belong to? In this article, we’ll explain the steps to identify it correctly. 

Steps to identify your collective labor agreement

Check your employment contract

The first step is to review your employment contract, as in most cases, the collective labor agreement must appear in it. The location of this information will depend on the type of contract. 

Check your payslip or the HR portal

Another option is to check your payslip, since in many cases it includes the code or the name of the agreement.

If your company has a Human Resources portal, this information might also be available there. 

Ask the Human Resources department

If after checking the previous options you still haven’t found information about your collective labor agreement, the solution will be to go directly to your company’s Human Resources department. 

Knowing which agreement applies to you is a worker’s right according to the Workers’ Statute, so they must provide you with this information. 

Search for the agreement code in the Official State Gazette (BOE)

Once we have the name or code of the agreement, it’s time to look it up in the Official State Gazette (BOE), where you will find the regulations, agreements, and updates related to working conditions.

How to interpret the information in the agreement?

What to do if I can’t find my collective agreement?

Contact the union

One option to learn about your collective agreement is to contact a union, which is an association of workers in the same sector that defends their labor, social, and economic interests against employers, with the goal of improving working conditions. 

These representatives can help you identify and obtain your collective agreement. 

Review the Workers’ Statute

Another option is to consult the Workers’ Statute, since it establishes the general labor law principles. These basic rules protect the worker, whether or not they are covered by a collective agreement.

Labor advisory service or labor inspection

The last option, if you still can’t find your collective agreement, would be to contact a labor advisory service or the Labor Inspectorate.

These professionals will check whether your company is complying with the agreements stated in the collective agreement and will provide guidance. 

The Labor Inspectorate is the body to turn to if the necessary measures are not being applied, and through which you can file an official complaint.
