Overtime and Working Hours in Portugal: Pay, Limits and Rest Rights

Portuguese employment law does not treat every extra minute at work as automatically payable overtime.

But it also does not allow employers to turn regular unpaid extra hours into a normal working arrangement simply because a worker is salaried.

The correct analysis begins with four questions:

• 1. What is your normal working schedule?
• 2. Did the work fall outside that schedule?
• 3. Was the overtime ordered or accepted by the employer?
• 4. Which pay rate and annual limit applies?

Normal working time

The general statutory maximum for normal working time is:

• eight hours per day;
• 40 hours per week.

Other lawful arrangements can affect the distribution of working time, including collective rules and specific working-time systems.

So do not assume that every day longer than eight hours automatically proves overtime.

First identify the actual lawful schedule.

What counts as overtime?

Portuguese law generally treats work performed outside the employee's work schedule as overtime.

The Labour Code also contains specific exclusions.

Examples can include:

• certain work performed under an exemption-from-schedule regime;
• work compensating agreed absences or interruptions;
• a limited exceptional 15-minute tolerance for completing tasks already started;
• limited professional training outside the schedule.

The label used internally by the company does not decide the issue.

If an employee is regularly required to work after the scheduled end time, the real working arrangement should be reviewed.

When can an employer require overtime?

Overtime is intended for defined situations, including:

• temporary and exceptional increases in workload where hiring another worker is not justified;
• force majeure;
• work indispensable to prevent or repair serious damage to the company or its viability.

The general rule is that a worker must perform lawful overtime when required.

But a worker can expressly ask to be excused where there are acceptable reasons.

Specific worker categories and collective arrangements can also affect the analysis.

Annual overtime limits

The Labour Code sets annual limits.

For ordinary full-time workers, the main limits include:

• 175 hours per year in a micro or small enterprise;
• 150 hours per year in a medium or large enterprise.

Collective regulation can increase those annual limits up to the statutory ceiling.

For part-time employees, a separate annual limit applies.

Daily overtime limits

On a normal working day, the general overtime limit is two hours.

On a weekly rest day or public holiday, overtime can generally extend up to the worker's normal daily working period.

A separate rule applies to a half-day complementary rest period.

Emergency or force-majeure situations can engage different statutory rules.

How is overtime paid?

The payment percentage changes after the worker exceeds 100 overtime hours in the calendar year.

Up to 100 overtime hours per year

On a normal working day:

• first hour or fraction: additional 25%;
• each subsequent hour or fraction: additional 37.5%.

On a weekly rest day or public holiday:

• additional 50% for each hour or fraction.

More than 100 overtime hours per year

On a normal working day:

• first hour or fraction: additional 50%;
• each subsequent hour or fraction: additional 75%.

On a weekly rest day or public holiday:

• additional 100% for each hour or fraction.

The correct calculation uses the applicable hourly remuneration.

What if the employer never gave a formal written overtime order?

The Labour Code does not require every valid overtime claim to begin with a formal written order.

Overtime payment can be due where the work was:

• previously and expressly ordered; or
• performed in circumstances where employer opposition was not reasonably foreseeable.

That second route matters where management knows that the work is being performed and allows it to continue.

However, evidence becomes critical.

What evidence helps prove overtime?

Useful evidence can include:

• timekeeping records;
• access-control records;
• shift schedules;
• emails sent outside normal hours;
• task-management logs;
• messages from managers;
• meeting records;
• system login history;
• witness evidence;
• payslips showing or omitting overtime.

Keep evidence before a dispute becomes formal.

Employer overtime records

Portuguese law requires employers to keep specific records of overtime.

The record framework is important because overtime is not supposed to be invisible informal labour.

If the employer's official records conflict with the employee's actual working pattern, that can become part of the dispute.

Compensatory rest

Overtime can also create rest rights.

Where overtime prevents the worker from taking the required daily rest, the employee can be entitled to equivalent paid compensatory rest to be taken within the following three working days.

A worker who performs overtime on the mandatory weekly rest day is entitled to a paid compensatory rest day, also generally within the following three working days.

Do not assume that all overtime creates the same rest entitlement.

Public holidays are not the same as weekly rest days

The Labour Code distinguishes:

• overtime on rest days or public holidays;
• normal work performed on a public holiday by a company allowed to operate that day.

The payment and compensatory-rest framework can therefore depend on why the employee was working.

What about "time off instead of overtime"?

Do not assume that an employer can simply replace statutory overtime pay with informal time off whenever it chooses.

The legality depends on the applicable Labour Code rules, collective regulation and the exact arrangement.

If the company says overtime is "included in the salary", check whether the worker actually has a valid regime that changes the ordinary overtime rules.

Isenção de horário does not mean unlimited free work

Some employees work under an exemption from the ordinary work schedule.

That regime can change how working time and overtime are assessed.

It does not mean an employer receives unlimited working hours without legal limits or remuneration consequences.

Review the actual contract and the form of schedule exemption.

What if overtime is not paid?

Unpaid overtime is an employment-credit problem.

The worker should:

• 1. document the hours;
• 2. calculate the amount;
• 3. request correction in writing;
• 4. preserve evidence;
• 5. decide whether formal legal intervention is required.

If the employer is also failing to pay ordinary salary, the issue can overlap with the separate unpaid-salary remedies.

Working time and health

Excessive working hours can also become a health and safety issue.

Portuguese working-time law includes daily and weekly rest protections for a reason.

A case involving chronic overtime should not be reduced only to arithmetic.

A practical overtime audit

1. Write down the contractual schedule

Identify normal start and end times.

2. Compare with actual hours

Use records, not memory alone.

3. Separate ordinary extra work from statutory exclusions

Not every extra minute is overtime.

4. Count annual overtime

Rates increase after 100 hours.

5. Identify rest-day and public-holiday work separately

Different rates can apply.

6. Check compensatory-rest rights

Especially if daily rest or mandatory weekly rest was affected.

7. Compare with payslips

Confirm what the employer actually paid.

8. Preserve evidence

Do this before system access disappears.

Common mistakes

"I am salaried, so overtime is never paid"

Incorrect. Salary status alone does not remove statutory overtime rights.

"Any time after eight hours is automatically overtime"

Not necessarily. Working-time arrangements and the actual schedule matter.

"My manager did not sign an overtime form, so I have no claim"

Payment can also arise where employer opposition to the work was not reasonably foreseeable.

"The overtime rate is always 25%"

Rates vary depending on the hour, the day and whether the worker has exceeded 100 annual overtime hours.

"Time off always replaces overtime pay"

Do not assume an informal substitution is legally valid.

Frequently asked questions

What is the normal maximum working week in Portugal?

The general statutory maximum for normal working time is eight hours per day and 40 hours per week, subject to lawful alternative arrangements.

How much is overtime paid?

Rates depend on whether the worker is below or above 100 annual overtime hours and whether the work is on a weekday, rest day or public holiday.

Can I refuse overtime?

The general rule is that lawful overtime must be performed, but a worker can expressly request exemption for acceptable reasons.

Does overtime need to be authorised?

The facts matter. Payment is due where overtime was expressly ordered in advance or performed in circumstances where employer opposition was not reasonably foreseeable.

Is there compensatory rest?

Yes in defined situations, including overtime that prevents daily rest and work on a mandatory weekly rest day.

Can I claim unpaid overtime together with unpaid salary?

Yes, they can form part of the wider employment-credit calculation.
