- A new employer may contact your former employer only with your specific, written and freely given consent.
- General consent covering “all former employers” is legally fragile because of the imbalance between candidate and employer.
- You may withdraw your consent at any time, request access to your data and file a complaint with the Commission for Personal Data Protection.
- A breach may cost up to EUR 20 million or 4% of worldwide turnover, plus compensation for the person affected.
A prospective employer may contact your former employer only if you have given specific, written and freely given consent in advance. Without such consent, the conversation amounts to unlawful processing of personal data. The penalty may reach EUR 20 million or 4% of the company's worldwide turnover, in addition to compensation for the person affected.
1. Why the Subject Is So Sensitive
Information on where you have worked and how you performed is part of your personal data, and the GDPR protects it, defining “any information relating to an identified or identifiable natural person” as personal data (Art. 4(1)). To process it, an employer needs a legal basis, and in recruitment this is almost always your consent (Art. 6(1)(a)).
2. Freely Given Consent and the Imbalance Trap
The GDPR specifies that consent is not valid where there is a “clear imbalance” between the parties (Recital 43). The relationship between a candidate and an employer is exactly that, since refusing may cost you the job. Clauses such as “you may contact all my former employers” are therefore legally fragile. What works is specific and limited consent, for example
“Yes, you may call George Ivanov, my line manager at X Ltd, solely for the purposes of this position.”
3. The Bulgarian Framework and the View of the Data Protection Commission
The Bulgarian Personal Data Protection Act applies the same principles. Data may be disclosed only on a statutory basis or with express consent. This is also set out in the guide on privacy in the workplace published by the Commission for Personal Data Protection, which stresses that without consent the employer should not disclose personal data to third parties.
4. Penalties – the Cost of a “Friendly Call”
- Art. 83 GDPR allows fines of up to EUR 20 million or 4% of worldwide turnover, whichever is higher.
- Art. 85 of the Personal Data Protection Act refers directly to these amounts.
- In practice, the National Revenue Agency was fined BGN 5.1 million for the 2019 personal data leak, proof that the fines are far from theoretical.
Both the company that carried out the check without a legal basis and the company that shared the information may be penalised.
5. How Candidates Can Protect Their Rights
a) Right of access – Art. 15 GDPR entitles you to ask any controller whether it processes your data and to whom it has disclosed it. A reply must be given within one month. Make the request in writing (by email, post or online form) and keep a copy.
b) Withdrawal of consent – Art. 7(3) GDPR provides that you may withdraw your consent “at any time”, and that withdrawal must be as easy as giving consent. After withdrawal, the employer must immediately stop all contacts and delete the information already collected, unless it has another legal basis to retain it.
c) Complaint to the Commission – if you believe your data has been used without a legal basis, you may file a complaint with the Commission for Personal Data Protection (Art. 77 GDPR). The procedure is free of charge. The Commission must inform you of the outcome and may order corrective measures and impose a fine.
d) Claim for compensation – Art. 82 GDPR and Art. 82 of the Personal Data Protection Act entitle you to compensation for material and non-material damage. The Court of Justice of the EU has confirmed that non-material damage (stress, damage to reputation) is also compensable, provided the consequences are proven.
6. What Employers Need to Know
- Obtain written, separate and specific consent for each reference check.
- Contact only the persons named by the candidate, no more and no fewer.
- A refusal to give consent should not automatically exclude the candidate.
- Keep all evidence, as this is the first thing the Commission will ask for in an inspection.
A conversation between a former and a new employer is lawful only after your freely given “yes”. Without it, the transfer of information breaches the GDPR and the Personal Data Protection Act and may prove costly in money, reputation and litigation.

Frequently asked questions
Can a prospective employer call my former employer without my consent?
No. Information about your previous employment is personal data, and in recruitment the legal basis is almost always your consent. Without it, the conversation is unlawful processing of personal data.
How can I give consent without taking risks?
Make it specific and limited. Name the person and the company that may be contacted and the purpose, for example “solely for this position”, instead of giving general consent for all former employers.
Can I withdraw my consent?
Yes, at any time, and doing so must be as easy as giving consent (Art. 7(3) GDPR). The employer must stop all contacts and delete the information collected, unless it has another legal basis to retain it.
What can I do if my data has been used without a legal basis?
You may file a free complaint with the Commission for Personal Data Protection and bring a claim for compensation for material and non-material damage under Art. 82 GDPR.
