The European Working Time Directive and junior doctor rotas: what schedulers must check

What the Directive sets

Directive 2003/88/EC concerning certain aspects of the organisation of working time applies to doctors in training as it does to other workers. It is a minimum: member states write it into national law, and they can go further. These are the articles a rota coordinator meets most often:

Article 2 defines "night time" as a period of at least seven hours that includes midnight to 05:00, and a "night worker" as someone who normally works at least three hours of their daily working time during it.

On-call counts as working time

The most important rulings for hospital rotas come from the Court of Justice of the EU:

• SiMAP (C-303/98, 2000): on-call time where doctors had to be present at the health centre was working time.
• Jaeger (C-151/02, 2003): on-call duty where a doctor must be physically present in the hospital is working time in its entirety, even if the doctor may sleep when not needed.
• Matzak (C-518/15, 2018): stand-by at home can also be working time when the constraints are severe. In that case a firefighter had to respond within eight minutes.
• Radiotelevizija Slovenija (C-344/19, 2021): stand-by is working time only if its constraints objectively and very significantly affect the worker's ability to manage free time and pursue their own interests.

For a scheduler, this means: resident (on-site) on-call is counted in full toward the 48-hour average, and those hours are not rest. Non-resident on-call from home sits in between: whether the waiting time counts depends on how tight the constraints are (response time, call frequency), and on national law and practice. Time actually worked during non-resident on-call always counts.

Derogations and compensatory rest

Hospitals have some room to depart from the rest rules. Article 17(3)(c)(i) allows derogations from Articles 3, 4, 5 and 8 (and the related reference periods in Article 16) for "reception, treatment and/or care provided by hospitals or similar establishments, including the activities of doctors in training". Article 17(4) allows similar derogations at shift changeovers.

The catch is Article 17(2): the worker must get equivalent periods of compensatory rest, or in exceptional cases appropriate protection. In Jaeger, the Court also held that compensatory rest must follow immediately after the working period it compensates. It cannot be stockpiled and taken next month. On the rota, that means a missed 11-hour rest after a busy on-call should be followed directly by the rest that was lost.

Reference periods: how the 48 hours is averaged

The 48-hour limit is an average, so the reference period matters as much as the number:

• Default (Art. 16(b)): up to 4 months.
• With derogations under Art. 17(3) or 18: up to 6 months (Art. 19).
• By collective agreement: member states may allow up to 12 months, for objective or technical reasons or reasons of work organisation (Art. 19).

Example: weeks of 60, 56, 40 and 36 hours average 48 over those four weeks. Whether the rota is compliant depends on the whole reference period, and in practice on the national limits that sit on top. In England, for example, the 2016 contract also caps hours at 72 in any 168, so a 76-hour week breaks the contract even if the average is fine.

The individual opt-out

Article 22 lets a member state allow individual workers to agree to work more than the 48-hour average. The conditions are strict: the worker must agree in advance, must not suffer any detriment for refusing, and the employer must keep up-to-date records of everyone who has opted out. Not every country allows it, and an opt-out covers the weekly average only. It does not remove the rest rules.

Doctors in training: the transition is over

When doctors in training were brought into the Directive, Article 17(5) gave member states a transition: a limit of 58 hours on average until 31 July 2007, then 56 hours until 31 July 2009. A further extension was possible for countries that notified the Commission; the UK used it for certain trainee posts, with a maximum of 52 hours, until 31 July 2011. Those transitional limits have all expired. Today the full 48-hour average applies to doctors in training as to any other worker, subject to the opt-out where national law allows it.

The UK after Brexit

The UK implemented the Directive through the Working Time Regulations 1998 (Great Britain; Northern Ireland has its own Working Time Regulations (Northern Ireland) 2016). These regulations did not fall away at Brexit:

• They remain in force. Since 1 January 2024, former retained EU law is known as "assimilated law" under the Retained EU Law (Revocation and Reform) Act 2023. CJEU judgments from before the end of 2020, such as SiMAP and Jaeger, remain part of UK law unless a higher UK court departs from them.
• The 48-hour average (regulation 4) is normally calculated over 17 weeks. For doctors in training, regulation 25A sets a reference period of 26 weeks.
• The individual opt-out is still available in the UK.
• The Employment Rights (Amendment, Revocation and Transitional Provision) Regulations 2023 changed record-keeping in Great Britain from 1 January 2024: employers must keep adequate records to show compliance, but the format is at their reasonable discretion and they need not record each worker's daily hours.

For resident doctors in England, the 2016 contract adds stricter limits on top of the regulations: 72 hours in any 168, 13-hour maximum shifts, no more than four consecutive nights followed by 46 hours of rest, and a weekend frequency limit. According to the BMA, doctors who opt out of the 48-hour average can still work no more than 56 hours on average. Our on-call rota template for doctors shows a rota built to these limits.

Checks to run before publishing

1. Write down which rules apply: national law, contract, collective agreement, and the reference period for each average.
2. Count resident on-call in full as working time. Decide, with HR, how non-resident on-call is counted under your national rules.
3. Check every gap between consecutive shifts against 11 hours, and mark where a derogation applies.
4. For every derogation, put the compensatory rest on the rota immediately after the shift that caused it.
5. Check weekly rest: 24 hours plus 11 per 7 days, or the 14-day equivalent.
6. Calculate the average weekly hours over the full reference period, with leave handled as your national rules require.
7. Identify night workers and check their average.
8. Keep a record of opt-outs and make sure the rota does not depend on someone opting out.
9. Re-run every check after each swap. Most breaches happen after publishing; see handling leave and swaps.
