Short answer. Yes. Offenses penalised under the Labor Code and its implementing rules prescribe in three (3) years. Unfair labor practice arising from Book V has a shorter, stricter deadline of one (1) year from the moment the practice accrues, after which the complaint is forever barred.
What the law says
Offenses penalized under this Code and the rules and regulations issued pursuant thereto shall prescribe in three (3) years.

Two different clocks, not one
The article sets two separate periods, and confusing them is the most common way a worker loses a case that was otherwise strong. The general rule covers offenses penalized under the Labor Code and under the rules and regulations issued pursuant to it: three years. The special rule covers unfair labor practice arising from Book V, the book on labor relations, and gives only one year from accrual. The statute is blunt about the consequence of missing the shorter period: the complaint is forever barred. That phrase is not decorative. Once the period lapses, no agency can revive the claim, however meritorious it may have been on the day it arose.
What this deadline does not cover
This article is about offenses — conduct the Labor Code itself penalises — and about unfair labor practice. It is not the deadline for every labor dispute you might have. Ordinary money claims arising from employer-employee relations, such as unpaid wages, overtime, holiday pay or service incentive leave, run on their own separate prescriptive period set elsewhere in the Code. Illegal dismissal claims likewise have their own timetable. So a worker who is told "you had three years" should check which kind of claim is actually being filed. Filing the right claim late is fatal; filing under the wrong theory can waste the period entirely while the correct clock quietly expires.
When the clock starts running
For unfair labor practice the statute fixes the starting point expressly — from accrual of such unfair labor practice. Accrual means the point at which the act complained of has actually happened and the injured party has a right to bring the complaint, not the later date on which the worker or union first felt its full effect or first got legal advice. Where the conduct is a single identifiable act, the year runs from that act. Where it is repeated, each distinct act may carry its own starting date. Because the difference between one reading and another can decide the case, the safest course is always to compute from the earliest defensible date.
What to do if the date is tight
Prescription binds everyone: the worker, the union, and the employer who wishes to raise it as a defense. It is not waived merely because the parties were still talking, and internal grievance discussions or a pending company investigation do not automatically stop the period. If the events are already months old, gather the documents that fix the dates — memoranda, notices, payslips, minutes — and get the complaint filed with the appropriate agency rather than waiting for a perfect case. A filed complaint can be amended and supported later; a barred one cannot be resurrected. If you are unsure which clock applies to your facts, book a consultation before the shorter one runs out.
