20 Jul Red flag from privacy authorities on monitoring of employees at work
Privacy risks can arise from the monitoring of usage of new technologies by employees at work and require a deep assessment especially in the light of the GDPR.
The Article 29 Working Party, a European advisory body made by European data protection authorities, issued an opinion on the usage of technologies at work which considers both current privacy laws and the General Data Protection Regulation.
The privacy principles applicable on monitoring of employees
According to the Article 29 Working Party:
- consent cannot and should not be the legal basis of the data processing at work – this is a quite often mistake, the potential consent from employees would not be freely given because of the employment relationship and therefore would not be valid;
- processing may be necessary for the performance of a contract where the employer has to process personal data of the employee to meet contractual obligations – this means that such legal basis cannot be used to justify data processing activities that go beyond what necessary for the performance of the employment contract;
- legitimate interest can be the legal basis of the data processing, but the chosen method or specific technology must be necessary, proportionate and implemented in the least intrusive manner possible and accompanied by mitigating measures to protect employees’ privacy – the balancing test necessary to rely on legitimate interest will be tricky and legitimate interest is definitely not a strong legal basis of data processing as it is open to different interpretations;
- employees should be clearly and fully informed of the processing of their personal data, including the existence of any monitoring under privacy laws – this is something already provided in Italy by the guidelines of the Italian data protection authority on the monitoring of the usage of Internet and emails on the workplace. The provision of adequate information on the type of data processing activities performed by means of technologies is not just a recommendation, but an obligation;
- principles of privacy by design, by default and of data minimisation shall be followed in building technologies that can monitor employees – this means that such technologies shall by default adopt the most privacy-friendly settings; and
- a privacy impact assessment has to be run when technologies can lead to high risk for individuals such as in case of potential profiling or decisions taken by means of automated systems.
The potential scenarios occurring on the workplace
The European privacy authorities adopted a very practical approach listing frequent scenarios occurring on the workplace and giving instructions on how potential needs of monitoring of employees should be handled:
1. Processing during the recruitment process
Information about a candidate on social media can be reviewed only if necessary and relevant to the performance of the job which is being applied for, can be performed only on social media related to business (e.g. LinkedIn, but not Facebook) and data should be deleted once it appears clear that an offer of employment will not be made or is not accepted by the individual concerned;
2. Screening of employees’ social media profiles
The review of social media profiles of employees, of their contacts/friends, opinions, beliefs, interests, habits, whereabouts, attitudes and behaviours should not take place and should not be required to employees and applicants.
3. Monitoring of electronic devices on the workplace
Privacy risks are not only connected the monitoring of emails and of Internet usage of employees, but new technologies include among others
- data loss prevention (DLP) tools,
- security applications and measures that involve logging employee access to the employer’s systems; and
- technologies enabling the monitoring of personal devices (e.g., PCs, mobile phones, tablets), that employees supply for their work in accordance with the Bring-YourOwn-Device (BYOD), as well as Mobile Device Management (MDM) technology which enables the distribution of applications, data and configuration settings, and patches for mobile devices.
In relation to the technologies above, the Article 29 Working Party recommends to
- run a privacy impact assessment in order to also understand whether the technology complies with the principle of proportionality and changes are needed to reduce the scale of the data processing; and
- provide employees with acceptable use policies that describe in details the processing that takes place and the rules of functioning of the system.
The second point above is at least arguable and risks to vanish in some circumstances the purpose of monitoring systems. Indeed, if in case of data loss prevention technologies, it is indicated, for privacy compliance purposes, in detail when it is triggered and in case of action triggering the monitoring a prior notification is sent to employees in order to enable him to cancel it, the risk is that the technology will “educate” the employee on how to avoid the alert to be triggered. This would result in a potential higher risk of data breaches that want to be avoid by means of such technologies.
Likewise, if it is given on the workplace the possibility to employees of sending private communications or in any case keeping such activities private, the risk is to create a channel for potentially illegal activities.
The above is difficult to explain in a regime that under the General Data Protection Regulation will oblige to implement “appropriate technical technical and organisational measures to ensure a level of security appropriate to the risk“, also introducing burdensome obligations in case of data breach.
The privacy authorities state that “prevention should be given much more weight than detection” which I fully agree. But in relation to the scenario above for instance, it is difficult to argue that employees should be given to mark some appointments as “private” and offered with “alternative unmonitored access” when in the 21st century basically everyone has a smartphone with a data plan and a private email.
In relation to the labor law approvals required for the usage of such technologies, a higher level of flexibility was given in Italy by means of the provisions of the so called Jobs Act.
4. Monitoring of usage by employees of electronic devices outside the workplace vs privacy law compliance
This is a practice that is becoming exponentially common with the growth of home working, remote working and “bring your own device” policies. The position of the Article 29 Working Party is the following:
Monitoring of home and remote working
There is a higher risk of unsecure usage of personal data by employees outside of working premises, but monitoring tools may be considered disproportionate and unjustified under privacy laws. The risk should be addressed in a proportionate and non-excessive manner, but the Article 29 Working Party does not give indications on how such goal can be achieved.
Bring your own device (BYOD)
It is prohibited to use technologies that perform a complete scanning of private devices and areas that are meant to be used for private purposes should be skipped.
Likewise monitoring the location and traffic of private devices used by employees may be justified by legitimate interest under privacy laws, but the technologies able to distinguish private and business usage shall be in place.
A secure transfer of data between the private device and the business network can be ensured by means for instance of a VPN, but again it should be avoided that such measure leads to privacy issues during private usage of the device.
An interesting point is that according to the Article 29 Working Party
“the employer must also consider the prohibition of the use of specific work devices for private use if there is no way to prevent private use being monitored—for example if the device offers remote access to personal data for which the employer is the data controller.“.
The above is expected to be the easier conclusion in order to avoid misbehaviours by employees and potential privacy breaches. If a device can be used only for business purposes, employers would definitely be in a stronger position.
Mobile device management
Mobile device management enables employers to locate devices remotely, deploy specific configurations and/or applications, and delete data on demand. A privacy impact assessment shall be run in order to avoid that such technologies can be used to monitor employees. Likewise, employees should be informed about the tracking and its features.
Wearable technologies tracking employees health data should be prohibited and employees’ consent is unlikely to be considered as a legal basis for the processing.
However, data protection authorities do not go too much into detail on the matter and in my view the issue should be reviewed taking into account the peculiarities of each case.
5. Processing operations relating to time and attendance
The crucial element on the usage of such technologies relates to the purposes for which collected data is used. If this is used for safety purposes, it is likely to be covered by legitimate interest, while if used to assess the performance of employees it is likely to trigger privacy risks.
6. Processing operations using video monitoring systems
The amount of information that can be collected by means of such technologies needs to be in line with the principle of proportionality and for instance employers should refrain from the use of facial recognition technologies.
7. Processing operations involving vehicles used by employees
The monitoring of vehicles used by employees is becoming very common, but the data processing performed by means of such technologies shall be proportional to avoid privacy law issues.
For instance an option to opt-out to the tracking should be given when the vehicle is used for private purposes or outside working hours, unless it is justified its continuous operation (e.g. in order to avoid the theft of the vehicle). But also in such case the monitoring shall be limited to what strictly necessary for the required purpose. And the same principle of proportionality shall be complied with in case of usage of technologies able to monitor the behaviour of employees in the vehicle.
A number of interesting points of discussion are raised by the opinion above and the General Data Protection Regulation is expected to lead to major challenges when it comes to the need to keep data secure and prevent that such security measures are in breach of employees’ privacy rights.
