GDPR-Compliant Time Tracking: What Employers Need to Know

Following recent EU and national court rulings, employers are now required to track their employees’ working hours. But how do you combine this obligation with the strict requirements of the GDPR? In this article, you’ll learn everything important.

The Double Challenge

Companies face two parallel requirements:

1. Time tracking obligation: Courts have ruled that employers must implement a system for recording working hours.

2. Data protection: The GDPR requires careful handling of personal data – and working hours are personal data.

What Data Can Be Collected?

Permissible Data

As part of time tracking, you may collect:

• Start and end of daily working hours
• Break times
• Overtime
• Project or client assignment (if operationally required)
• Location for mobile employees (with restrictions)

Impermissible Data

You may not collect:

• Detailed activity logs
• Private break content
• Performance measurements without objective reason
• Continuous location tracking

The 7 GDPR Principles in Time Tracking

1. Lawfulness

You need a legal basis for processing. For time tracking, this is:

• Art. 6(1)(c) GDPR (legal obligation)
• Art. 6(1)(f) GDPR (legitimate interest)

2. Purpose Limitation

Collected time data may only be used for specified purposes:

• ✅ Payroll
• ✅ Proof for authorities
• ✅ Project billing
• ❌ Covert performance monitoring
• ❌ Creating personality profiles

3. Data Minimization

Only collect the truly necessary data. Ask yourself:

• Do I really need this information?
• Is there a less invasive alternative?
• Can I manage with less data?

4. Accuracy

The collected data must be correct. This means:

• Employees should be able to verify their times
• Corrections must be possible
• Incorrect data must be rectified

5. Storage Limitation

Data may only be stored as long as necessary:

Data Type	Retention Period
Payroll documents	6 years
Overtime records	Varies by agreement
GPS data	As short as possible

6. Integrity and Confidentiality

You must implement technical measures:

• Data encryption
• Access controls
• Secure passwords
• Regular backups

7. Accountability

You must be able to demonstrate compliance:

• Documented processes
• Processing register
• Data protection impact assessment (if necessary)

Practical Implementation

Create a Processing Register

Document your time tracking in the processing register:

Processing Activity: Time Tracking
Purpose: Fulfilling time tracking obligation, payroll
Categories of Data Subjects: Employees
Categories of Data: Working hours, break times, location data if applicable
Retention Periods: 6 years after end of calendar year
Technical Measures: Encryption, access controls

Fulfill Information Obligations

Inform your employees according to Art. 13 GDPR about:

1. Controller: Who is responsible for data processing?
2. Purpose: Why is data collected?
3. Legal basis: On what grounds?
4. Recipients: Who receives the data?
5. Storage duration: How long is data stored?
6. Data subject rights: What rights do employees have?

Regulate Data Processing Agreements

Using external software? Then you need a Data Processing Agreement (DPA) with the provider. This regulates:

• Instruction dependency
• Technical measures
• Subcontractors
• Deletion after contract end

Checklist: Is Your Time Tracking GDPR-Compliant?

✅ Legal basis documented?

✅ Employees informed?

✅ Only necessary data collected?

✅ Access rights defined?

✅ Deletion periods established?

✅ Technical security ensured?

✅ DPA concluded with software provider?

✅ Processing register updated?

✅ Data subject rights ensured?

✅ Data protection officer involved?
