How many hours of rest between shifts?

“How many hours of rest must there be between shifts?” is one of the most frequent questions when a company organises rotating shifts, split shifts or night work. The short answer is 12 hours between the end of one shift and the start of the next. There is one scenario in which that rest can drop to 10 hours, and a golden rule worth keeping in mind: that rest is never paid out, it is taken. Here is how it looks from the HR manager’s point of view.

Quick answer

Situation	Minimum rest between shifts
General rule (art. 34.3 ET)	12 hours
Sectors with special working hours (RD 1561/1995)	10 hours with alternative rest
Replacing the rest with money	Prohibited (except at the end of the contract)
Maximum ordinary working time per day	9 hours of actual work
Workers under 18	12 hours between shifts and max. 8 hours a day

What the Workers’ Statute says

Article 34.3 of the Workers’ Statute is direct:

“Between the end of one working day and the start of the next, at least twelve hours must elapse.”

That same article establishes that ordinary working time cannot exceed 9 hours a day, unless a collective agreement or an agreement between the company and the workers’ representatives sets out a different distribution, always respecting that 12-hour rest between shifts.

Put another way, the company can organise working time with considerable flexibility, but there is a floor it cannot touch. If a worker finishes at 22:00, they cannot clock in again before 10:00 the following day.

The 12-hour rest is a non-waivable right

This is where most companies go wrong. The rest between shifts is not a negotiable condition that staff can “give up” in exchange for something. Article 3.5 of the Statute prevents a worker from validly disposing of the rights that the law or the collective agreement recognise as non-waivable.

That has a very clear practical consequence: the rest cannot be replaced by an amount on the payslip. The High Court of Justice of the Canary Islands confirmed this when it found against RIU Hotels for rest periods of less than 12 hours between shifts, annulling an agreement that compensated the reduced-rest days with around 2.42 euros a day. It made no difference that the arrangement had been in force for decades and was accepted in practice: swapping rest for money is void.

When it can drop to 10 hours

The only real room to reduce the rest between shifts lies in Royal Decree 1561/1995 on special working hours. In sectors such as hospitality, shift work, transport or work at sea, the rest between shifts can be reduced to a minimum of 10 hours.

That reduction does not come for free, though. Royal Decree 1561/1995 requires the hours of rest not taken to be offset with equivalent alternative rest within the reference periods the regulation itself sets out. And its Article 2.2 closes the door to paying for it:

“The compensatory rest periods provided for in this Royal Decree may not be replaced by financial compensation, except where the employment relationship ends.”

For a hospitality business with shifts, or for any business that chains late closings with early openings, the operating rule is simple: if the rest is reduced, you have to be able to point to the alternative rest on the rota that offsets it, not to an amount on the payslip.

Does overtime count?

Yes, and there is a detail here that often slips by. The 12-hour rest is measured between the actual finishing time and the actual starting time the next day. If an employee extends their shift with overtime, the rest clock starts counting from that later finish, not from the end of their theoretical schedule.

This means a busy spell in the afternoon can eat into the window before the next day’s start. Whoever plans the shifts has to watch both things at once: the overtime limit and the rest between shifts.

How to prove you have complied

Everything above rests on one piece of data the company has to be able to prove: what time each person left and what time they arrived the following day. That information only exists if there is a reliable time record.

Without a record, the company cannot prove it respected the 12 hours, nor that it provided the alternative rest when it reduced them to 10. In a claim or an inspection, that lack of traceability always works against it, just as it does with the burden of proof for overtime. With the new Royal Decree on digital time tracking, still pending publication in the Official State Gazette (BOE), that daily traceability will become directly enforceable.

How Cleverfy solves it

Cleverfy is time tracking and working-time software for SMEs and the self-employed that lets you see at a glance whether the rest between shifts is being respected.

• Real clock-in and clock-out records with a timestamp per worker, to measure the exact rest from one shift to the next.
• Flexible shifts and rotas, with split, night or irregular shifts, without losing sight of the legal minimum.
• Overtime totalled separately, so you know when extra hours eat into the next day’s rest.
• Daily and monthly reports in one click, ready for payroll, for the workers’ representatives or for the Labour Inspectorate.
• Accessible, retained history that proves compliance if a claim ever arises.

Conclusion

Between the end of one shift and the start of the next there must be 12 hours of rest as a general rule, reducible to 10 hours only in the sectors covered by RD 1561/1995 and always with alternative rest, never with money. It is a non-waivable right the company is obliged to guarantee. And as with everything in time tracking, complying is half the job: the other half is being able to prove it with a reliable record.
