Employee Monitoring — What Is Allowed in Switzerland
Employee monitoring in Switzerland means observing work activity, IT use, or productivity—by camera, software, GPS, or keystroke logging. Swiss law permits this only if it is proportionate, serves a legitimate business purpose, and employees are informed in advance. Monitoring that is covert, excessive, or invasive violates the Federal Constitution (article 13) and the revised Data Protection Act (revDSG). Your obligation is to be transparent: disclose monitoring in the employment contract or employee handbook, keep data secure, and delete it promptly. The most common mistake is installing surveillance software without warning staff first.
Monitoring employees means tracking their work activity, location, communications, or IT use through technical or manual means. Swiss employers can do this—but only within strict legal boundaries.
When monitoring arises: you suspect theft or data theft; you want to measure productivity; you use company devices; you manage remote or field staff; or you enforce IT security policy. Swiss law requires you to act transparently and proportionately.
What Swiss Law Allows
The Swiss Federal Constitution (article 13) guarantees privacy. The revised Data Protection Act (revDSG) applies to all employee data. Together they permit monitoring only if it is proportionate to the business need, serves a legitimate purpose (security, productivity, compliance), and employees know it is happening.
Monitoring of IT systems—emails, internet use, file access—is generally allowed on company devices during work hours if disclosed. Location tracking is allowed for field staff or deliveries if necessary for the job. Hidden cameras, keystroke logging, or covert GPS are almost never proportionate.
- Disclose monitoring in the employment contract or employee handbook before or at hire
- Monitor only what serves a clear business purpose (not personal curiosity)
- Use the least invasive method that achieves the goal
- Retain data only as long as needed; delete it promptly
- Do not monitor private communications (personal email, messaging apps outside work)
- Ensure data is encrypted and access is restricted to authorized staff
Your Obligation as Employer
Transparency is mandatory. Employees must know in advance what is monitored, how, and why. A vague reference in an old handbook is not enough. If monitoring changes—new software, GPS devices, camera installation—inform staff in writing and allow reasonable time to object.
You must also limit access to monitoring data, use it only for the stated purpose, and delete it on schedule. If you use an external vendor (monitoring software, IT security firm) they must sign a data processing agreement. Breaching these rules exposes you to claims for damages under revDSG.
- Include monitoring details in the employment contract or update employee handbook in writing
- Inform staff if monitoring scope changes; give notice before implementation
- Restrict access to monitoring data to managers or IT staff who need it
- Use data only for the purpose stated at disclosure; do not repurpose it
- Document why monitoring is necessary (business case, security threat, legal requirement)
- Sign a data processing agreement with any external vendor handling monitoring data
The Most Common Mistake
Installing monitoring software—keystroke loggers, screen recorders, GPS trackers, or email archiving—without telling employees first. This is a breach of article 13 and revDSG, and can trigger civil lawsuits or labor court claims. Even if the software serves a legitimate purpose, covert use destroys trust and legal standing.
A close second: monitoring employees' private messages, personal email, or off-hours activity. Swiss courts view this as disproportionate invasion of privacy. Stick to work devices, work hours, and work-related communications.
- Never install monitoring software without explicit advance notice in writing
- Do not monitor personal email, WhatsApp, or private accounts, even on company devices
- Do not monitor employees outside working hours unless the role demands it (on-call, emergency response)
- Do not use monitoring data for decisions (discipline, termination) without documenting the business reason
- If you discover misconduct via monitoring, be ready to explain why monitoring was in place
- Consult a Swiss employment lawyer before rolling out new monitoring; revDSG compliance is complex
Frequently asked questions
- Can I use monitoring software to check if remote staff are working?
- Yes, if it is proportionate and disclosed. Monitoring active work time (time tracking, task completion, application use during work hours) is generally allowed if staff know about it and it serves a clear business need. Hidden keystroke logging or constant webcam recording is not proportionate. Consider less invasive alternatives: regular check-ins, deliverables, time sheets. If you choose software, disclose it in writing before use and document the business reason.
- Can I use GPS to track field staff or deliveries?
- Yes, for employees whose role requires field travel (service technicians, couriers, sales reps). GPS tracking must be disclosed in the employment contract or handbook, used only during work hours, and limited to business routes. Tracking employees' private vehicles or home location goes beyond work and is likely disproportionate. Inform staff of the tracking policy, the device used, and how long data is retained.
- What happens if I monitor without consent?
- You breach article 13 of the Federal Constitution and the revDSG. Employees can sue for damages, file a complaint with the cantonal data protection officer, or challenge discipline based on covert monitoring in labor court. A court may rule the monitoring illegal and void any discipline based on it. The financial and reputational cost far exceeds the benefit of hidden surveillance. Always disclose first.
