Weaponizing Data Privacy: How Competitors and Ex-Employees Use SARs as Legal Leverage

Imagine you open your email and you find a polite email. In it, someone wants a copy of all the personal information you are holding. There is no lawsuit and no threat. But just a subject access request – SARs. Yet, beneath the smooth surface, what if this simple request becomes the company’s next legal headache? What if a former employee is using privacy rights to challenge management decisions?  Welcome to the emerging grey area of data privacy!

Yes, SARs are becoming something more than transparency tools. Definitely, they are designed to facilitate employees. Yet, sometimes they create immense pressure for organizations. The reasons may be many. Commercial rivalries and employment disputes are among them. Hence, it is pivotal that businesses understand when data access becomes a potential instrument of legal leverage.

The Hidden Power of SARs

A Subject Access Request is an individual’s legal right to obtain personal data held by the organization. Under UK GDPR and the Data Protection Act 2018, individuals can ask businesses to explain how their personal information is processed. Moreover, they can request access to that information. Generally, you have one month to reply to such a request. Certainly, it’s a noble right born of trust and transparency. 

However, even the finest blade can be turned in the wrong hand. This happens when a request comes wrapped in grievance, a redundancy dispute, or a commercial rivalry.

What might someone actually be looking for through a SARs?

• Internal emails discussing their employment, performance, or professional conduct.
• HR records covering disciplinary actions, grievances, and workplace disagreements.
• Management discussions relating to redundancy or other private decisions
• Recruitment records containing assessments and interview feedback
• Communications involving their participation in confidential business projects
• Personal information shared with external advisors or third-party organizations.

The Catch? It’s true that SARs provide access to personal data. Yet, it is not an access pass to corporate documents, trade secrets, or confidential business tactics. 

When Former Employees Turn Data Requests into Legal Ammunition

An employee’s departure may not be the end of workplace disagreements. The chapter may still be open. Definitely, there will be compensation disagreements, discrimination allegations, etc that can continue even after the exit interview. This is where Subject Access Requests enter the picture. 

Imagine there is a senior manager who believes that his dismissal was unfair. They could submit a SAR requesting internal emails, performance assessments, meeting notes, and management correspondence. 

What might they discover? Probably, they could see inconsistencies between the official explanation they received and internal discussions. In fact, that is enough for them to prepare for legal proceedings.

Common motivations behind employee-related SARs include:-

• Gathering information before pursuing employment tribunal proceedings.
• Identifying inconsistencies in performance assessments and dismissal explanations.
• Examining internal discussions surrounding redundancy or disciplinary decisions.
• Supporting negotiations involving employment disputes and settlement agreements
• Understanding how managers handled workplace complaints or grievances.

Competitors and Data Intelligence Game

Can a competitor directly use someone else’s SAR to obtain confidential business information? Not ordinarily. As a matter of fact, SAR rights belong to individuals and cannot simply be accessed by rival organizations to access another firm’s records.

However, consider this situation. A senior employee leaves your organization and joins a direct competitor. And, before or after leaving, they submit a Subject Access Request seeking personal information connected to their previous role.  The request might contain references to strategic projects, important client relationships, commercial negotiations, or internal business initiatives. 

So, does that mean that a previous employee can access all these details? Certainly not. In fact, personal data access does not create the right to trade secrets, corporate confidential information, or unrelated third-party information. 

So, where could the complications arise?

• Personal data embedded within commercially sensitive email conversations.
• References to clients and colleagues in employment-related correspondence.
• Internal discussions mentioning confidential projects and strategic responsibilities.
• Records containing third-party personal information that requires appropriate protection.

The Pressure Points: How SARs Can Disrupt Business Operations

A strategically timed SAR can definitely create considerable pressure. This can happen even before the organization discloses the single document. Why? Because responding involves much more than downloading emails. In fact, businesses need to search multiple systems and retrieve archived records.  They should also review thousands of documents. In addition, they should identify personal information and apply appropriate redactions.

Pressure Point	Possible Business Consequence
Extensive data searches	Increased workload for HR, IT and compliance teams
Employment disputes	Additional scrutiny of management decisions
Confidential records	Complex disclosure and redaction decisions
Tight deadlines	Greater pressure on internal disclosures
Regulatory exposure	Potential consequences of non-compliance
Reputational concerns	Increased sensitivity around workplace practices

Red Flags: When Does a SAR Cross The Line?

Not every demanding SAR is a red flag. However, certain patterns may indicate an attempt to turn privacy rights into corporate pressure tactics.

Under UK GDPR. Organizations may refuse requests that are manifestly unfounded or excessive. However, each case requires careful scrutiny. Remember, a demanding request does not automatically mean malicious intent.

• The request is very broad, asking for everything with no details
• It arrives with a legal threat, a complaint letter, or settlement talks
• A third party sends it with no proof
• The same person repeats it again and again for the same data
• Someone offers to drop the request in return for money or a favour
• The request has a clear business link to a rival

Not every weaponized SAR looks alike.

Feature	Ex Employee	Competitor
Typical Motive	Build a case at a tribunal or win a bigger payout	Dig up business secrets or dig up your work
Favourite Targets	HR files, manager emails, performance notes, chats	Internal messages, pricing talks, client emails
Common Tactic	Huge “give me all my data” demand	Request sent by a person, director, or go-between with a business link
Timing	Soon after a complaint, redundancy, or exit	Before a bid, a pitch, or a fight over a poached staff
Biggest Risk	Frank internal opinions ending up in a court	Sensitive business details leaking through poor blacking out

Turn Vulnerability into Vigilance: Six Corporate Defense Strategies

Should businesses wait for complicated Subject Access Requests before strengthening their data protection practices? Certainly not.

Six Safeguards Worth Implementing

• Centralize SAR Management- Establish clear procedures across HR, IT, Legal, and Compliance teams
• Organize Employee Records- Maintain accurate information and appropriate data retention schedules.
• Strengthen Access Controls- Restrict sensitive employee and commercial information to authorised personnel.
• Improve Internal Communication- Encourage managers to maintain professional and factual workplace correspondence.
• Review Before Disclosure – Identify personal data, third-party information, and applicable legal exemptions.
• Train Employees- Help teams recognize SARs, regardless of how requests arrive.

Beat the Clock: Managing SAR Deadlines

A SAR request is also a race against time. Furthermore, under UK GDPR, there is one month to respond. However, complex requests may qualify for an extension of up to two additional months with appropriate notification.

Follow the Six Step Response Strategy-

• Register: Record the request and receipt date.
• Assess: Understand its scope and its requirements.
• Search: Retrieve relevant records across business systems.
• Review: Examine personal data and applicable exemptions.
• Redact: Protect information that should not be disclosed.
• Respond: Deliver the relevant information securely within the deadline.

Beyond IT: Making Data Privacy a Boardroom Priority

Evidently, data protection is no longer just an IT responsibility. On the other hand, it is something that the whole business system should prioritize.

Three priorities can strengthen organizational resilience.

• Data visibility: Know where personal information resides and how it is processed.
• Legal readiness: Prepare teams to assess requests and apply relevant exemptions
• Corporate accountability: Build a culture of responsible communication and privacy awareness.
• Continuous Monitoring: Regularly review data protection practices to identify vulnerabilities and strengthen compliance measures.

Final Thoughts

Subject Access Requests are essential privacy rights. However, the battle for corporate information is no longer fought only in boardrooms or courtrooms.  Sometimes it begins with a single request in your inbox. Furthermore, SARs can bring hidden workplace tensions, legal disagreements, or information management weaknesses into the spotlight. In fact, organizations that treat data privacy as a tick-box exercise may find themselves playing catch-up. 

The takeaway? Don’t wait for a data dispute to expose your weakness. Write your compliance story before someone writes it for you.
