In short
The Labor Standards Bureau (NNT) of the Department of Labor and Human Resources exists to guarantee non-unionized private-sector employees the rights in Puerto Rico’s protective labour legislation. It receives complaints, carries out inspections and processes claims for wage differences, dismissal compensation, vacation, sick leave, Christmas bonus and agricultural sharecropping, among others. The most direct route is to write to normas@trabajo.pr.gov with your phone number, the municipality where you live, the name and address of the employer you want to report, and what the guidance is about. You can also complete form NNT-99AA, the Contact Sheet, and send it to that same address, or go to one of the six Area Offices: San Juan, Arecibo, Mayagüez, Ponce, Caguas and Humacao. Most claims arrive through a worker’s direct complaint, not through an inspection.
What is it?
The NNT is established by Section 17 of Ley Núm. 15 of 14 April 1931, the Organic Act of the Department of Labor and Human Resources. Its responsibility is to guarantee non-unionized private-sector employees full enjoyment of the rights set out in Puerto Rico’s protective labour legislation. To that end it conducts inspections, processes claims, answers enquiries, handles complaints, offers guidance through conferences and seminars, and issues permits and licences. The Department explains why it matters: through the claims it refers to the Legal Affairs Bureau and to the Mediation and Adjudication Office, the NNT gives access to justice to a working class without resources, and promotes balance in the labour relations of employees who have no union representative.
Who can do it?
The NNT serves non-unionized private-sector employees. The Department estimates Puerto Rico’s workforce at 1,198,000 people, all of whom it is obliged to serve if needed, and says it serves roughly 200,000 workers. If you have a union representative and your claim is under a collective agreement, the route is the agreement’s and, once the grievance committee is exhausted, arbitration through the Conciliation and Arbitration Bureau. If your matter is employment discrimination, the forum is the Antidiscrimination Unit, not this one.

Step by step
Step 1: Put a name to what happened to you
The NNT publishes the list of matters it advises on, and it is worth reading in full because many people never file simply because they did not know their situation had a name. They are: unjustified dismissal; vacation and/or sick leave; wages, overtime, meal period, illegal deductions, tips; Christmas bonus; religious accommodation; and workplace harassment. The claims the Bureau processes also cover wage differences, dismissal compensation — what many people call “la mesada” — agricultural sharecropping and miscellaneous cases protecting the reinstatement of employees who are absent after an accident or occupational disability.
Step 2: Write to normas@trabajo.pr.gov
It is the route the NNT publishes for both enquiries and complaints. In your message include your name, your phone number and the municipality where you live, so the assigned official can contact you. If it is a complaint, add the name and address of the employer you want to report and state what the guidance is about.
Step 3: Or use Contact Sheet NNT-99AA
The NNT publishes form NNT-99AA, the Contact Sheet, precisely so you do not have to remember everything in an email. It provides the basic information needed to bring a claim. You complete it and send it to the same address, normas@trabajo.pr.gov, so an official can contact you and determine whether there is a cause of action based on what you set out.
Step 4: Or go to the Area Office that covers you
There are six and each covers specific towns. Metro, at Edificio Prudencio Rivera Martínez, 9th floor, 505 Ave. Muñoz Rivera, San Juan, PR 00918, tel.

Step 5: What happens next: complaint, investigation, claim
The NNT distinguishes between a complaint and a claim. Complaints are the problems workers bring in and, although they often do not end in a claim, the Bureau says they require investigation just as if they had. Claims arise from inspections or, in the great majority of cases, from a worker’s direct complaint. Inspections are carried out by Labor Standards Investigators in manufacturing, services, commerce, construction and other industries, to verify employer compliance and correct any violation committed to workers’ detriment. From there the case can be referred to the Legal Affairs Bureau or to the Mediation and Adjudication Office.
Step 6: If a former employer owes you and cannot find you
There is something almost nobody knows about. Ley Núm. 77 of 17 April 1952 requires every employer to deposit with the Secretary of Labor whatever it owes on any account to former employees it has not located or whose whereabouts it does not know, starting ninety days from when it became aware of the debt. If a worker dies, the employer must also deposit what it owed them, and that sum is distributed among the heirs under the Civil Code. Deposits are handed over at the NNT Area Offices. If you worked years ago somewhere that closed, or you moved without leaving an address, ask about the Fondo de Reclamaciones at your Area Office.
Where to do it
By email to normas@trabajo.pr.gov, by phone to the Area Office covering your municipality, or in person at one of the six Area Offices: San Juan, Arecibo, Mayagüez, Ponce, Caguas and Humacao. The Fondo de Reclamaciones has its own mailing address: Negociado de Normas de Trabajo, Fondo de Reclamaciones, PO Box 195540, San Juan, PR 00919-5540.
How long it takes
What to do if something goes wrong
If your matter is employment discrimination — age, race, sex, pregnancy, sexual harassment, disability, sexual orientation, gender identity, being a domestic violence victim, being a service member or veteran — the forum is the Antidiscrimination Unit, not the NNT. If you are unionized and your claim is under a collective agreement, the route is the grievance committee and then arbitration. If what you want is an administrative judge to decide your wage, vacation, bonus or dismissal claim, the Mediation and Adjudication Office is a separate and free forum. This guide does not say how long you have to file, how long the investigation takes or how much you might receive: DTRH publishes none of the three on this page. Ask the official about the limitations period on your first call, because that is the fact that can cost you the whole claim. PRFácil gives no legal advice.
Common mistakes
- Not filing because you believe you need a lawyer or money.
- Writing to normas@trabajo.pr.gov without your phone or municipality: without those the assigned official cannot reach you.
- Not giving the name and address of the employer you want to report.
- Going to the wrong Area Office: each covers specific towns.
- Taking a discrimination case to the NNT instead of the Antidiscrimination Unit.
- Letting time pass without asking what the deadline to file is.
- Assuming that if the employer closed there is nothing to be done: the Ley 77-1952 Claims Fund exists.
Frequently asked questions
Do I need a lawyer to file?
The NNT page nowhere requires a lawyer at any stage: you write, call or go to the Area Office and an official assesses whether there is a cause of action. The Department expressly describes its role as giving access to justice to a working class without resources.
What can I complain about?
The NNT lists: unjustified dismissal; vacation and sick leave; wages, overtime, meal period, illegal deductions and tips; Christmas bonus; religious accommodation; and workplace harassment. Its claims also cover wage differences, dismissal compensation and agricultural sharecropping.
What if I am in a union?
The NNT serves non-unionized private-sector employees. If you have a collective agreement, the route is the agreement’s grievance committee and, once exhausted, arbitration before the Conciliation and Arbitration Bureau.
What is the Claims Fund?
Under Ley Núm. 77 of 17 April 1952, every employer must deposit with the Secretary of Labor what it owes former employees it has been unable to locate, from ninety days after learning of the debt; and what it owed a deceased worker, to be distributed among the heirs. Deposited amounts are handed over at the NNT Area Offices.
