In short
The Working Mothers Protection Act (Act 3 of March 13, 1942, as amended) gives a pregnant private-sector worker a rest of 4 weeks before childbirth and 4 weeks after, paid by the employer at full salary, computed on the last 6 months’ average and payable when the rest begins. With medical certification that you can work until one week before delivery, you may opt to take only 1 prenatal week and extend the postnatal rest up to 7 weeks. The employer must reserve your job, and dismissing a pregnant worker is presumed unjustified: the employer must prove otherwise. An employee adopting a preschool-age minor (5 or under, not enrolled in school) gets the same benefits; adopting a minor aged 6 or older, up to 5 weeks. If a postnatal complication arises, the rest extends up to 12 additional unpaid weeks, with the job reserved.
What is it?
It is the working mother’s right to paid rest around childbirth, at the employer’s expense. The base structure is 8 weeks: 4 before and 4 after delivery. The pay is the full salary — not half, as the law originally said — computed on the average of what you earned in the 6 months before the rest (or your salary at the time, if you have less than 6 months), and the employer must pay it when the rest begins, not in installments. The law applies to every woman employed for a wage, salary or any form of compensation in offices, commercial and industrial establishments and public service companies, including term-contract employees while the employment relationship lasts. Government employees are governed by their own personnel rules, which this guide does not cover.
Who can do it?
It covers the "obrera" under the law’s own broad definition: every woman employed for a wage, salary, term contract or any other form of compensation, in any office, commercial or industrial establishment or public service company. The protections apply to term-contract employees while the employment relationship subsists — and if a real expectation of continuity was created for you, they extend beyond the date the contract was supposed to end. The rest and benefits also apply if you are on vacation, sick leave or another leave when the time comes, as long as the bond remains in force. And adoption maternity is expressly covered: the same benefits as childbirth if you adopt a preschool-age minor (5 or under, not enrolled in school); up to 5 weeks if you adopt a minor aged 6 or older.

Step by step
Step 1: Decide how to split the 8 weeks
The base is 4 weeks before and 4 after. If you prefer saving time for after the birth, you can take only 1 prenatal week and extend the postnatal ones up to 7, presenting medical certification that you can work until one week before delivery; the physician must consider the kind of work you do. If the birth comes early and you had not started (or not used up) the prenatal rest, that time is not lost: it moves to the postnatal rest, paid the same.
Step 2: Hand in the medical certificate and get paid at the start
The rest is activated by presenting the medical certificate to the employer, which your prenatal care physician must issue free. Payment for the full period — full salary, computed on the previous 6 months’ average — is due when the rest begins. If the employer wants to pay it "through payroll as usual", they are paying late: the law says at the start.
Step 3: If the birth is late, prenatal leave extends with pay
When the probable delivery date was misestimated and you used up the 4 prenatal weeks without giving birth, you are entitled to have the prenatal leave extended at full pay until the birth occurs. The 4 postnatal weeks remain intact.
Step 4: After the birth: early return or extension for complications
You may ask to return after the first 2 postnatal weeks with a medical certificate that you are fit — waiving the remaining weeks. At the other extreme, if a postnatal complication prevents you from working beyond the 4 weeks, the employer must extend the rest up to 12 additional weeks, provided you present the medical certification before the rest expires; those additional weeks are unpaid, but with the job reserved.
Step 5: If the employer fails to comply: claim
Denying the rest, not paying it, not reserving your job, or firing you over the pregnancy has three consequences in the law: civil liability for double the damages (or $1,000 to $5,000 if they cannot be quantified), reinstatement, and even criminal liability with a $1,000 to $5,000 fine or 30 to 90 days in jail. In every dismissal of a pregnant worker the action is presumed unjustified and the employer must prove otherwise — lower output due to pregnancy is not just cause. To claim wages or the rest you can use the summary labor claims procedure (Act 2 of 1961); if you prevail, the judgment includes costs and attorney’s fees. Guidance: Department of Labor.
Where to do it
The rest is claimed directly from the employer, with the medical certificate. If the employer fails to comply, guidance and claims at the Department of Labor and Human Resources (trabajo.pr.gov) or through the summary labor procedure in court. Public employees are governed by their own personnel rules, not this law.
How long it takes
What to do if something goes wrong
If you are fired while pregnant, remember the presumption: the law presumes the dismissal was unjustified and the burden of proving otherwise is the employer’s. Keep everything in writing — the medical certificate handed in, the date you notified, the communications. If the employer alleges you produced less because of the pregnancy, the law expressly says that is not just cause. If you adopt and the employer says the leave is "only for childbirth", show them the law: adoption of a preschooler gives the same benefits, with the 30-day notice requirement and evidence of the proceedings. And if what you need is the lactation period upon returning, that is another law with its own guide: the Lactation Code.
Common mistakes
- Believing the leave is unpaid or half-pay. Since the amendments to Act 3, the employer pays the full salary, computed on the last 6 months’ average.
- Not demanding payment when the rest begins: the law says it is due at the start, not week by week.
- Waiving weeks unintentionally: returning after 2 postnatal weeks with a medical certificate means waiving the remaining weeks.
- Missing the complication deadline: the postnatal complication’s medical certification must be presented before the rest expires to trigger the up-to-12-week extension.
- In adoptions, not giving the employer the 30-day notice with evidence of the proceedings: the law requires it to claim the leave.
- Thinking a temporary contract leaves you out: the law covers term contracts while the relationship lasts, and beyond if a real expectation of continuity was created.
Frequently asked questions
Who pays the leave, the employer or the government?
The employer. Act 3 imposes on them the obligation to pay the full salary during the rest, when it begins. It is not a government benefit nor disability insurance.
Does it apply if I work for the government?
Act 3 covers workers in offices, commercial and industrial establishments and public service companies — the private sector. Public employees have maternity leave under their own personnel rules, which this guide does not detail because we did not read those sources; ask your human resources office.
What if I adopt?
If you adopt a preschool-age minor — 5 or under, not enrolled in a school institution — you get the same maternity leave benefits as an employee who gives birth. If you adopt a minor aged 6 or older, the leave is up to 5 weeks, counted from when you receive the minor into the family. In both cases you must notify the employer 30 days in advance and submit evidence of the adoption proceedings.
Can the employer fire me when the leave ends?
The employer must reserve your job during the rests and cannot fire you without just cause over the pregnancy or adoption. Refusing to reinstate you after the birth or adoption creates civil liability for double the damages and the right to be restored to your job.
