Work schedule in Portugal: who sets it and when it changes

In Portugal, the work schedule is set by the employer, but under tight rules: prior consultation, 7 days notice when it changes, and one protection many people miss: an individually agreed schedule cannot be changed without your consent (Article 217(4) of the Labour Code).

This guide explains who sets the schedule, when it can change, and what the law requires for schedule exemption, shift work and night work.

Schedule, normal working period and operating hours: which is which

The work schedule sets the start and end times of the working day, the breaks and the weekly rest (Article 200(1)). It is the concrete frame of your day. Start and end can even fall on consecutive days: someone who starts at 23:00 and leaves at 07:00 has a valid schedule.

The limits on quantity, meaning the 8 hours per day and 40 per week of Article 203, the adaptability ceilings and the 48 hour average cap, are covered in the guide on working hours limits. Here we deal with distribution: who controls the clock.

Who sets the schedule, and with which limits

Setting the work schedule is the employer's call (Article 212(1)). But the same article imposes three priorities:

• Safety and health first. Protecting the worker takes priority in schedule design.
• Work-life balance. The employer must make it easier to combine work with family life. It is a legal criterion, not a favour.
• School and training. Workers who study or attend professional training must have that made easier.

Before schedules are defined or organised, the workers' committee (or, failing that, union delegates) must be consulted (Article 212(3)). Skipping the priorities or the consultation is a serious administrative offence.

The result goes into the working time map, posted in a visible place at the workplace (Articles 215 and 216), showing start and end times, breaks, the weekly rest day and the applicable collective agreement. This map sits alongside the working time records and the written statement of your working conditions: the schedule is part of that mandatory information under Article 106.

Can my employer change my schedule?

The question that fills labour courts. The answer has three layers (Article 217):

Layer 1, the rule. A change follows the same process as the original schedule: consultation with the workers involved and their representatives, and posting in the company 7 days in advance, or 3 days in a micro business (Article 217(2)). This applies even under adaptability regimes.

Layer 2, the short exception. Changes lasting up to one week skip the prior posting, provided they are recorded in a dedicated book, with a note that representatives were consulted, and the employer uses this route no more than 3 times per year (Article 217(3)).

Layer 3, the shield. An individually agreed schedule cannot be changed unilaterally (Article 217(4)). If the concrete hours are in your contract, or were agreed with you in a provable way, any change needs your consent.

There is also a little known bonus: if the change increases your costs (an extra travel pass, driving because there is no train at the new hour), you are entitled to financial compensation (Article 217(5)). Breaching any of these rules is a serious administrative offence.

[Common interpretation:] Portuguese case law holds that merely writing the practised hours in the contract is not always enough to prove the schedule was "individually agreed"; what counts is real negotiation between the parties. If your contract fixes concrete hours and you want to use this shield, keep anything showing those hours were a condition for you to accept the job.

The rest periods no schedule can erase

Whatever the schedule, some minimums always apply:

• A rest break of 1 to 2 hours, so you never work more than 5 consecutive hours, or 6 when the daily period is longer than 10 hours (Article 213). Collective agreements can reduce, remove or extend the break; beyond that, only ACT can authorise it, at the employer's request and with your written agreement.
• Daily rest of 11 consecutive hours between two working days (Article 214), with narrow exceptions: exempt directors, force majeure, continuous operation activities with compensatory rest.
• Weekly rest of at least one day per week (Article 232); details in the working hours limits guide.
• Silence after hours: the employer must refrain from contacting you during rest periods, except force majeure (Article 199-A, created by Law 83/2021). Breaching it is a serious offence; penalising workers who do not pick up counts as discrimination.

Working remotely? The same rules apply, and schedule exemption plays a special role there, covered next.

Schedule exemption: paid freedom

Exemption from work schedule (isenção de horário, IHT) is not "work whenever you like", nor "work for free until late". It is a regime with three locks (Articles 218, 219 and 265):

Written agreement only, and only for certain cases (Article 218): management or director roles (and positions of trust, supervision or support to them), preparatory or complementary work that by nature can only happen outside the schedule, and telework or regular work outside the company without immediate supervision. Collective agreements can add other cases.

Three types (Article 219): no subjection to the maximum limits of the normal working period; a set increase of hours per day or week; or keeping the agreed normal period. If nothing is chosen, the first and widest type applies. In every type, the exemption does not touch weekly rest, public holidays or the 11 hours of daily rest (Article 219(3)).

It is paid (Article 265): at least the value of 1 overtime hour per day, or 2 hours per week in the type that keeps the normal period. Only directors and managers can waive this supplement.

Mind the myth: workers with the widest exemption type do not earn overtime on normal days (Article 226(3)), but in the limited types, anything beyond the agreed period is overtime (Article 226(2)), with the premiums explained in the overtime pay guide.

Shift work and night work

When operating hours exceed the limits of the normal working period, the employer organises shifts with different staff (Article 221). Key rules: each shift respects the maximum hour limits; you only change shift after the weekly rest day (Article 221(4)); in continuous operation there is at least one rest day in every period of 7 days; and the employer keeps a separate record of who is in each shift. Workers' preferences must be taken into account "as far as possible" (Article 221(2)): a weak standard, but one you can invoke if you have children or study, together with the priorities of Article 212.

Night work is, in the absence of a collective agreement, work performed between 22:00 and 07:00 (Article 223(2)); the agreement can set another period, with a minimum of 7 and a maximum of 11 hours that includes the interval between 00:00 and 05:00. It pays a 25% premium over equivalent day work (Article 266(1)).

Anyone doing at least 3 hours of night work per day is a night worker (Article 224(1)) with specific protections: free and confidential health exams before starting and then at least once a year, risk assessments every 6 months, and the right to move to day work when a health problem is linked to night work (Article 225). In activities with special risks, the cap is 8 hours in any period of 24 (Article 224(4)).

The 7 schedule rules at a glance

For employers: what ACT checks first

If you manage a team, you answer for five concrete points:

1. Working time map posted and complete (Articles 215 and 216): a missing map is a serious offence; failing to post it, a light one.
2. Prior consultation of workers' structures when drawing up and changing schedules (Articles 212 and 217): without a consultation record, the change is born flawed.
3. 7 days notice for changes, and a dedicated book for short changes, with the yearly limit of 3 uses.
4. Exemption by written agreement with the specific supplement on the payslip (Articles 218 and 265): verbal or unpaid exemptions are a classic source of fines and of labour credits claimed years later.
5. Separate shift records and rotation only after the weekly rest day (Article 221).

The full picture of employer duties, from health and safety to social security filings, is in the employer obligations checklist and the hiring guide. Fine brackets are explained in the ACT complaint guide.

How it all connects

The schedule is the distribution; the hour limits are the quantity. Whatever falls outside the schedule is overtime, and it must appear in the working time records, which you can consult at any moment. Flexibility tools like the hours bank change the quantity per period; the continuous working day for parents and grandparents and the parental flexible schedule (Article 56) change the distribution in your favour. And if the schedule you actually work does not match the paper, start with the mandatory written statement and, if needed, an ACT complaint is free.

This guide summarises Articles 197 to 228 and 265 to 268 of the Portuguese Labour Code as of July 2026. Collective agreements may set different rules, including more favourable ones; in a concrete dispute, the legal text and the applicable collective instrument prevail.
