In short
The Mediation and Adjudication Office (OMA) was created by Ley Núm. 384 of 17 September 2004 within the Department of Labor and Human Resources. Its purpose is to ensure that non-unionized private-sector employees have a quasi-judicial forum where their labour claims reach a just, fast and inexpensive resolution. It has concurrent jurisdiction with the Court of First Instance: you can bring your claim for wages, unjustified dismissal, vacation, sick leave, Christmas bonus, working hours, day of rest, working mothers’ leave or reinstatement there, without going to court. DTRH lists the service as free and allows parties to appear on their own behalf, including corporations and partnerships. The OMA offers two distinct things: mediation, which is voluntary and confidential, and adjudication, where an Administrative Judge decides. Phones (787) 754-5858 exts. 1260, 1261 and 1205, or (787) 754-5353 ext. 12605; email oma@trabajo.pr.gov.
What is it?
The OMA is the administrative forum implementing the public policy of harmonizing labour disputes, through alternative dispute resolution methods and an adjudicative procedure. It has concurrent jurisdiction with the Court of First Instance over claims under nine statutes: Ley Núm. 17 of 17 April 1931, on payment of wages; Article 5A of Ley Núm. 45 of 18 April 1935, for violation of the right to reinstatement; Ley Núm. 3 of 13 March 1942, on working mothers’ leave; Ley Núm. 289 of 9 April 1946, on payment of wages on the day of rest; Ley Núm. 379 of 15 May 1948, on working hours; Ley Núm. 148 of 30 June 1969, on the Christmas bonus; Ley Núm. 80 of 30 May 1976, for unjustified dismissal; Ley Núm. 180 of 27 July 1998, for wages, vacation and sick leave; and Ley Núm. 4 of 26 January 2017, the Labor Transformation and Flexibility Act.
Who can do it?
The OMA’s stated purpose is to give a forum to non-unionized private-sector employees. Your claim’s subject matter must fall under one of the nine statutes the OMA administers. That the jurisdiction is concurrent with the Court of First Instance means the same matter can also be taken to court; the OMA is the free, no-lawyer-required alternative, not a prerequisite to court.

Step by step
Step 1: Check that your claim is on the list
The OMA does not handle just any labour problem: it handles those under nine specific statutes. If you are owed wages, it is Ley 17-1931 or Ley 180-1998. If you are owed vacation or sick leave, Ley 180-1998. If your Christmas bonus went unpaid, Ley 148-1969. If you were dismissed without just cause, Ley 80-1976. If it is about working hours, Ley 379-1948; if about day-of-rest pay, Ley 289-1946. If it is working mothers’ leave, Ley 3-1942. If you were denied reinstatement, Article 5A of Ley 45-1935. And Ley 4-2017, the Labor Transformation and Flexibility Act, is also within it.
Step 2: Call or write to the OMA
The published phones are (787) 754-5858, extensions 1260, 1261 and 1205, and (787) 754-5353, extension 12605. The fax is (787) 765-4013 and the email oma@trabajo.pr.gov. If your case comes from a prior Labor Standards Bureau or Antidiscrimination Unit investigation, say so: the adjudicative procedure is subsequent to and independent of those investigations.
Step 3: Mediation: voluntary, confidential and privileged
Mediation is a non-adversarial, non-adjudicative intervention in which a mediator acts as facilitator so the parties reach a mutually acceptable agreement. What matters is the protection: the information or documentation the parties offer and the mediator’s working file cannot be demanded in judicial or administrative adjudication proceedings, including the OMA’s own adjudicative process. And no party may disclose, wholly or partly, what was said in mediation, on pain of sanctions, absent the written consent of all parties. You can speak frankly without it being used against you later.
Step 4: Adjudication: an administrative judge decides
If there is no agreement, adjudication is the procedure in which an Administrative Judge determines each party’s rights, obligations or privileges. It is subsequent to and independent of the investigative process of the Labor Standards Bureau and the Antidiscrimination Unit and, in certain circumstances, is reached after exhausting mediation. The OMA lists the rights safeguarded: timely and adequate notice of the complaint; filing an answer to the complaint; cross-examining witnesses and examining the evidence against you; appearing on your own behalf or through a lawyer; presenting evidence; an impartial Administrative Judge; an impartial adjudication; and a decision based on the administrative record.
Step 5: You can go on your own, and so can the employer
Among the advantages the OMA publishes is the flexibility of administrative procedures: parties may appear on their own behalf, including corporations, partnerships and other legal entities. That last part is unusual — in court corporations normally must be represented — and it means neither you nor the employer is forced to pay a lawyer to take part. DTRH also lists the service as free.
Where to do it
Mediation and Adjudication Office of the Department of Labor and Human Resources. Phones (787) 754-5858, extensions 1260, 1261 and 1205, and (787) 754-5353, extension 12605. Fax (787) 765-4013. Email oma@trabajo.pr.gov.
How long it takes
What to do if something goes wrong
If your claim does not fall under any of the nine statutes, the OMA is not the forum. For employment discrimination it is the Antidiscrimination Unit; for a wage complaint not yet investigated, the Labor Standards Bureau; if you are unionized under a collective agreement, arbitration through the Conciliation and Arbitration Bureau. The OMA’s jurisdiction is concurrent with the Court of First Instance: the same matter can be taken to court, and choosing between the two forums is a decision with consequences this guide does not weigh for you. Nor does this guide say how long you have to file, how long the process takes or what remedies the OMA grants: DTRH does not publish that on this page. PRFácil gives no legal advice and represents nobody.
Common mistakes
- Not filing because you believe you must pay a lawyer: the service is free and you may appear on your own.
- Taking a discrimination case to the OMA, which belongs to the Antidiscrimination Unit.
- Believing you must go through the OMA before going to court: the jurisdiction is concurrent, not tiered.
- Staying silent in mediation for fear it will be used later: what is said there is confidential and privileged.
- Disclosing what was discussed in mediation without all parties’ written consent: that is subject to sanctions.
- Letting time run without asking what the deadline to file the complaint is.
Frequently asked questions
What does it cost?
DTRH lists the OMA’s service as free, among the advantages it publishes for both parties alongside access to justice and the elimination of lengthy investigations and costly lawsuits.
Can I go without a lawyer?
Yes. The OMA publishes that parties may appear on their own behalf, including corporations, partnerships and other legal entities, and in the adjudicative process it expressly lists the right to appear on one’s own or through a lawyer.
Is the OMA the same as the court?
No, but it has concurrent jurisdiction with the Court of First Instance over claims under those nine statutes. It is a quasi-judicial forum inside the Labor Department, where an Administrative Judge decides on the administrative record.
Can what I say in mediation hurt me later?
No. The information or documentation the parties offer and the mediator’s working file cannot be demanded in judicial proceedings or in administrative adjudication proceedings, including the OMA’s own adjudicative process. Moreover, no party may disclose it without all parties’ written consent, on pain of sanctions.
