Employee monitoring laws in Spain
Yes — the Workers' Statute expressly allows the employer to adopt monitoring measures — but Spanish law conditions it on express, prior and explicit information to staff and to their representatives, and the courts throw out evidence gathered without it.
Who has to agree before you start
The fact that decides the timeline, and the one that differs most between countries.
The workforce must be consulted first
Under LOPDGDD art. 87 employers must involve workers' representatives in setting the criteria for use of digital devices, and art. 64 of the Workers' Statute gives the works council information and consultation rights over measures affecting staff. Representatives are consulted rather than asked to consent.
Representatives must be informed and consulted, or negotiated with, before the decision is taken. They cannot block it, but doing it in the wrong order is itself the breach — and in France skipping it is a criminal offence independent of any data-protection issue.
GDPR with the Ley Orgánica 3/2018 (LOPDGDD), which contains dedicated digital-rights-at-work articles, alongside the Estatuto de los Trabajadores.
The law that applies in Spain
Named so you can check us, and so your own counsel has somewhere to start.
| Instrument | What it requires |
|---|---|
| LOPDGDD art. 87 | Recognises employees' right to privacy in the use of digital devices made available by the employer, requires criteria for their use to be set with the participation of workers' representatives, and requires employees to be informed of those criteria. |
| LOPDGDD art. 88 | Establishes the right to digital disconnection outside working hours, which constrains monitoring that would extend the working day in practice as well as on paper. |
| Estatuto de los Trabajadores art. 20.3 | Allows the employer to adopt the measures it considers most appropriate to verify compliance with employment obligations, with due regard for human dignity — the provision monitoring is grounded in, and the one the proportionality test qualifies. |
| Estatuto de los Trabajadores art. 64.5 | Gives the works council the right to be informed and to issue a report before the employer implements decisions on work organisation and control, including the introduction of monitoring systems. |
How a rollout is done here
- Set the criteria for use of company digital devices with the participation of workers' representatives, as art. 87 requires, rather than issuing a policy and notifying it.
- Inform employees expressly, precisely and in advance of what is monitored, by what means and for what purpose. Spanish courts treat this as a condition of the evidence being admissible.
- Inform the works council and allow it to issue its report before implementation.
- Document the proportionality assessment against the Constitutional Court's standard: the measure must be suitable, necessary and balanced.
- Run a DPIA for systematic monitoring and record the legitimate-interests basis.
What gets a rollout refused
- Generic notice. A clause saying company systems 'may be monitored' has repeatedly been found insufficient; the information has to be specific about the means and the purpose.
- Retrofitting the notice after an incident, then trying to rely on the data. This is the classic Spanish evidence-exclusion fact pattern.
- Monitoring outside working hours, which runs into the art. 88 disconnection right.
- Treating art. 20.3 as an unconditional permission. It is the starting point, not the end of the analysis, and the proportionality test does the real work.
Monitoring staff in Spain — questions
How specific does the notice to employees have to be?
Specific enough that an employee knows what is captured and why before it happens. Spanish case law has turned on the difference between a general statement that systems may be monitored and an express, precise statement of the monitoring in place. The second is what makes resulting data usable.
Do workers' representatives have a veto?
No. LOPDGDD art. 87 requires their participation in setting the criteria and ET art. 64.5 gives an information and report right, but neither is a consent requirement of the German, Austrian or Dutch kind.
Does the right to digital disconnection affect time tracking?
It constrains monitoring that would in effect extend the working day, and it sits awkwardly with tools that continue to record outside agreed hours. A capture window bounded to working hours is the straightforward way to stay clear of the issue.
