Data concerning health may include your body temperature, health symptoms and other screening information in connection with the Company’s health and safety plans and protocols, including screening required to access Company offices/facilities and other measures designed to prevent the transmission of COVID-19 or other infectious diseases. 

We ask that you avoid submitting Sensitive Information, unless such information is legally required and/or the Company requests you to submit such information.

Any information you submit through the Careers Site must be true, complete and not misleading.  Submitting inaccurate, incomplete or misleading information may lead to a rejection of your application during the recruitment process or disciplinary action including immediate termination of your employment.  In addition, it is your responsibility to ensure that the information you submit does not violate any third party’s rights.

4.  How we use and disclose EU and UK Personal Information

Legal Basis for Processing

We will only use EU and UK Personal Information when the law allows us to.  Most commonly, we will use your EU and UK Personal Information in the following circumstances: 

  • where it is necessary in order to take steps at your request prior to entering into an employment contract; 
  • where it is necessary to comply with a legal obligation (including, in respect of Sensitive Information,  obligations under employment law) on us; and
  • where it is necessary for our legitimate interests (or those of a third party) and your interests and fundamental rights do not override those interests.  For example, the Company has a legitimate interest in conducting certain background checks on applicants to ensure that it is offering employment to those individuals whom it considers are most likely to be successful when working for the Company.

We may also use your EU and UK Personal Information in the following situations, which are likely to be rare:

  • where it is necessary to protect your (or someone else's) vital interests (and, in the case of Sensitive Information, where you are incapable of consenting);
  • where it is necessary for us to defend, prosecute or make a claim against you, us or a third party; and
  • in the case of Sensitive Information, where you have made the information public.

In particular, we may use your Sensitive Information, such as health/medical information, in order to accommodate a disability or illness during the recruitment process, and reduce the risk of transmission of COVID-19 or other infectious diseases should you be visiting the Company offices, your diversity-related EU and UK Personal Information (such as race or ethnicity) in order to comply with legal obligations relating to diversity and anti-discrimination, and your criminal conviction data only where it is appropriate (given the role for which you are applying) and we are legally able to do so.

Purposes of Processing

We process EU and UK Personal Information for the following purposes:

  • Managing Workforce: Managing recruitment and assessing your suitability, capabilities and qualifications for a job with us, processing your application and performing background checks if we offer you a job, such as credit checks, anti-fraud checks and checks to prevent fraud and money laundering;
  • Communications: Facilitating communication with you regarding your application; 
  • Taking legal action: Pursuing legal rights and remedies, defending litigation and managing any internal complaints or claims, conducting investigations and complying with internal policies and procedures; and
  • Compliance and safety: Complying with legal (including, in respect of Sensitive Information, obligations under employment law) and other requirements, such as record-keeping and reporting obligations, conducting audits, compliance with government inspections and other requests from government or other public authorities, responding to legal process such as subpoenas. This includes complying with applicable public health guidelines and requirements related to the prevention and control of COVID-19 or other infectious diseases, as well as ensuring the health and safety of employees by controlling access to and monitoring our physical premises (e.g. by requiring health screenings to access Company offices/facilities).

There may be more than one purpose that justifies our use of your EU and UK Personal Information in any particular circumstance.

We will only use your EU and UK Personal Information for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose.  If we need to use your EU and UK Personal Information for an unrelated purpose, we will notify you and explain the legal basis which allows us to do so.

If you fail to provide certain EU and UK Personal Information when requested, we may not be able to review your application, or we may be prevented from complying with our legal obligations.

To ensure that EU and UK Personal Information is sufficiently protected when transferred outside the EEA and UK the Company has put in place protective measures. Further information regarding the Company’s protective measures is available from our Data Protection Officer.

6. Data Security

The Company has put in place procedures to deal with any suspected data security breach and will notify you and any applicable regulator of a suspected breach of your EU and UK Personal Information where we are legally required to do so.

The Company’s retention periods for EU and UK Personal Information are based on business needs and legal requirements.  We retain EU and UK Personal Information for as long as is necessary for the processing purpose(s) for which the information was collected, as set out in this Notice, and any other permissible, related purposes. For example, we may retain certain information to comply with regulatory requirements regarding the retention of such data, or in the event a litigation hold is imposed.  When EU and UK Personal Information is no longer needed, we [either irreversibly anonymise the data (and we may further retain and use the anonymized information) or] securely destroy the data.

Your decision to complete the form and your answer will not harm you in any way.
