Data protection and employment records

How to manage personal data relating to employees

Data protection compliance efforts are often focused on commercial or public-facing aspects of an organisation’s activities. Making sure core data protection principles and requirements are met when collecting and handling the data of customers, members, supporters, students, patients, and so on. However the personal data held relating to employees and job applicants doesn’t always get the same level of attention.

Handling employees’ personal information is an essential part of running a business, and organisations need to be aware and mindful of their obligations under the UK GDPR and Data Protection Act 2018. As well as, of course, obligations under employment law, health and safety law, and any other relevant legislation or sector specific standards.

A personal data breach could affect employee records. Employees can raise complaints about an organisation’s employment activities and employees (or former employees) can raise Data Subject Access Requests which can sometimes be complex to respond to. All of which can expose gaps in compliance with data protection laws. In some organisations employee records may represent the highest privacy risk.

Employee records are likely to include special category data and more sensitive information such as:

DE&I information (such as information relating to race, ethnicity, religion, gender, age, sexual orientation, etc)
disabilities and/or medical conditions
health and safety records
absence and sickness records
performance reviews and development plans
disciplinary and grievance records
occupational health referrals
financial information required for payroll

Alongside the core HR records, employees may be present on other records – such as CCTV, any tracking of computer / internet use, and so on. All of which need careful consideration from a data protection standpoint. Also see monitoring employees.

In my experience, while the security of employee records may often be taken into consideration, other core data protection principles might sometimes be overlooked, such as:

Lawfulness

It’s necessary to have a lawful basis for each processing activity. Many activities may be necessary to perform a legal obligation or covered under the contract of employment with the individual. However, the contract may not cover every activity an organisation has requiring the use of employee data. It should be clearly determined where legal obligation or the contract is appropriate for any given activity and confirm any activities where you may instead need to rely on other lawful bases, such as legitimate interests or consent.

Special category data

To handle medical information, trade union membership and diversity, equity and inclusion (DE&I) activities, and any other uses of special category data, it’s necessary to determine a lawful basis, plus a separate condition for processing under Article 9. Handling special category data

Data minimisation

The principle of data minimisation requires employers to take steps to minimise the amount of personal information about their employees to what is necessary for their activities and not hold additional personal information ‘just in case’ they might need it.

Data retention

Employee’s data should not be kept longer than necessary. There are statutory retention requirements for employment records in the UK (and many other jurisdictions), which set out how long they must be kept. But these laws may not cover all types of activities you may have for employment data. Once you set these retention periods, they need to be implemented in practice, i.e. regular reviews of the data you hold for specific purposes and securely destroy records you no longer need. These may be electronic records on IT systems or perhaps physical HR records languishing in boxes in a storeroom! You may wish to refer to our Data Retention Guidance

Transparency

Employees are entitled to know the ways in which their employer uses their personal data, the lawful bases, the retention periods and so on. The requirements for privacy notices must be applied to employees, just like external audiences. This necessary privacy information may be provided in an Employee Privacy Notice or via an Employee Handbook.

Risk assessments

Data Protection Impact Assessments are mandatory in certain circumstances. In other cases they might be helpful to conduct. Organisations mustn’t overlook DPIA requirements in relation to employee activities. For example, any monitoring of employees which might be considered intrusive or the use of biometric data for identification purposes.

Record keeping

Appropriate measures need to be in place to make sure employee records are being handled lawfully, fairly and transparently and in line with other core data protection principles. It’s difficult to do this without mapping employee data and maintaining clear records of the purposes you are using it for, the lawful bases, special category conditions and so on, i.e. your Record of Processing Activities (RoPA). The absence adequate records will make the creating a comprehensive privacy notice rather challenging.

Training

Whilst we’re on the topic of employees, let’s also give a mention to training. All employees handling personal data should receive appropriate information security and data protection training. It’s likely those in HR / People teams handling employee data on a daily basis will benefit from specialist training beyond the generic online training modules aimed at all staff.

To help you navigate data protection obligations the ICO has published new guidance on handling employee records, which provides more detail on what the law requires and regulatory expectations.

Finally, don’t forget data protection compliance efforts need to extend beyond employees to job applicants, contractors, volunteers and others who perform work-related duties for the organisation.
