New technologies for workplace monitoring allow companies to organise work, protect assets, measure productivity and improve security. But in employment relationships, not everything is allowed: any monitoring system must respect privacy, data protection, dignity and the legal limits applicable to workers.
The balance lies in allowing the employer to exercise management and control powers without turning technology into disproportionate surveillance. Companies must consider the Spanish Workers’ Statute, the GDPR and the Spanish Data Protection Act (LOPDGDD).
In this article we will discuss...
What is workplace monitoring through new technologies?
Technology-based workplace monitoring includes tools such as CCTV, geolocation, digital time recording, monitoring of corporate devices, access logs, productivity tools, analysis of professional communications and data loss prevention systems.
These tools may be lawful if they pursue a legitimate purpose, are necessary, proportionate and properly notified to employees. Problems arise when systems are installed without a clear legal basis, without information, excessively or for purposes different from those communicated.
Employer control powers and legal limits
Article 20.3 of the Spanish Workers’ Statute allows employers to adopt monitoring and control measures to verify compliance with employment obligations. However, those measures must respect workers’ dignity and fundamental rights.
From a data protection perspective, companies must apply the principles of lawfulness, transparency, minimisation, purpose limitation and security. It is not enough for a tool to be useful: it must be appropriate for the intended purpose and permanent surveillance cannot replace proportionality.
CCTV at work
CCTV may be used for security or employment control, but it requires prior information, visible signage and a clear policy covering purpose, controller, retention and rights. Cameras should generally not be installed in rest areas, changing rooms, toilets or spaces where the expectation of privacy is especially high.
If images may be used for disciplinary purposes, the company should have informed workers about the system and its possible employment-control purpose, except in legally exceptional cases.
Employee geolocation
Geolocation of vehicles, phones or corporate devices must be justified by a real need: route organisation, safety, service control or asset protection. It should not be used to track employees outside working time or outside the work context.
The company must provide express, clear and unequivocal information about the system, purpose, legal basis, retention period and available rights.
Monitoring email, computers and corporate tools
Monitoring corporate digital devices requires a prior internal policy. The company must explain what uses are allowed, what controls may be carried out, for what purpose and under what safeguards. Without such a policy, reviewing emails, files or digital activity may create significant risk.
A good policy should distinguish between professional use and permitted or prohibited personal use, limit access to what is necessary and document who may review information and in which cases.
Artificial intelligence and productivity tools
Artificial intelligence, workforce analytics and productivity measurement tools create additional risks: automated decisions, bias, profiling, continuous evaluation and loss of transparency. Before implementing them, companies should carry out an employment and data protection risk assessment.
If the tool may affect working conditions, performance evaluation or disciplinary decisions, transparency, human oversight and proportionality become even more important.
Checklist for implementing workplace monitoring systems
- Define the specific purpose of the monitoring system.
- Check and document the legal basis.
- Apply proportionality: use the least intrusive measure possible.
- Inform employees in advance and, where appropriate, worker representatives.
- Update internal policies on devices, CCTV, geolocation or AI.
- Limit access and retention of collected data.
- Assess whether a DPIA is needed where high risk exists.
- Review provider contracts if external tools are involved.
Frequently asked questions
Can a company review an employee’s computer?
It may do so in certain cases, but there should be a clear prior policy on the use of digital tools and possible controls. The review must be proportionate and limited to the intended purpose.
Is prior information required before installing cameras?
Yes. Workers must be informed about the CCTV system, its purpose and the basic data protection information. Areas especially protected by privacy should be avoided.
Can an employee be geolocated all day?
Not indiscriminately. Geolocation must be limited to the work-related purpose that justifies it and should not extend to periods outside working time or service provision.
Can a company use AI to evaluate productivity?
It may be possible, but it requires transparency, proportionality, human oversight and risk analysis. If relevant employment decisions are involved, stronger safeguards are needed.
Conclusion
New technologies can help companies, but they must be implemented with a clear legal strategy. Informing, documenting, limiting and periodically reviewing monitoring systems is essential to avoid employment disputes, data protection fines and loss of internal trust.
