Employers hold significant amounts of employee personal data and must comply with the UK GDPR and the Data Protection Act 2018. Getting this wrong can lead to ICO enforcement action, fines, and damage to employee trust.
Key Principles for Employee Data
- Lawfulness, fairness, and transparency — employees must know what data you collect and why
- Purpose limitation — only use data for the purposes you've told employees about
- Data minimisation — only collect what you need
- Accuracy — keep employee records up to date
- Storage limitation — don't keep data longer than necessary
- Security — protect employee data with appropriate technical and organisational measures
Lawful Basis for Processing
For employee data, the main lawful bases are:
- Contract performance — processing payroll, managing absence, administering benefits
- Legal obligation — PAYE, right-to-work checks, health and safety records
- Legitimate interests — performance management, internal communications (requires a balancing test)
- Consent — rarely appropriate in employment due to the power imbalance, but may apply for optional benefits or photos
Special Category Data
Some employee data requires additional protection:
- Health and medical information
- Trade union membership
- Racial or ethnic origin
- Religious beliefs
- Biometric data (fingerprint scanners)
Practical Requirements
- Provide an employee privacy notice explaining what data you process and why
- Conduct Data Protection Impact Assessments (DPIAs) for new HR systems or monitoring
- Respond to employee Subject Access Requests (SARs) within one month
- Implement data retention schedules and delete records when no longer needed
- Train staff who handle employee data
