Imagine you’ve just accepted a new job. You’re excited about the opportunity, but before leaving your current company, you decide to save a few documents that might come in handy later. Maybe it’s a spreadsheet you spent months developing, a collection of project notes, customer information, or presentations that you created yourself.

You figure there’s no harm in keeping copies. After all, you did the work, right?

Unfortunately, creating a document doesn’t necessarily mean you own the information inside it. Taking confidential files to another employer can create serious legal and compliance problems, even if you never intended to misuse your past work.

A recent dispute between OpenAI and Apple shows just how complicated things can become when confidential information follows an employee to a new workplace.

What Happened Between OpenAI and Apple?

On October 14, 2026, OpenAI accused a former employee of transferring more than 100 confidential files to personal accounts before returning to work at Apple.

Included data allegedly contained information about an unreleased OpenAI device, including engineering details, manufacturing information, and product plans. OpenAI also alleged that the former employee presented information about its unreleased product to senior Apple executives.

Apple disputes the allegations, saying it has policies designed to prevent employees from using confidential information belonging to previous employers. The company also stated that it had found no evidence supporting OpenAI’s claims.

The allegations remain unresolved, but they highlight a problem that can affect employees at practically any company: What happens to confidential information when someone changes jobs?

Your Work Doesn’t Always Belong to You

When you create something at a job, why can’t you just take it with you when you leave?

Depending on your employment agreement, company policies, and applicable laws, those records may belong to your employer. The same applies to internal presentations, pricing information, product designs, financial reports, and other confidential documents.

You can’t design a store banner and then bring it home when you quit. Why wouldn’t the same apply to company documents and other digital information?

Some data may also qualify as a trade secret, meaning it has commercial value because it isn’t publicly known and therefore the company takes additional steps to protect it. Using that information without authorization could violate confidentiality agreements, employment policies, or trade secret laws.

Mistake #1: Sending Company Files to Personal Accounts

Maybe you’re switching jobs and want to save examples of your previous work for your portfolio, so you email yourself a few presentations, spreadsheets, and reports.

What’s the harm?

Unfortunately, you’ve potentially moved confidential information outside the systems that your employer controls. Your personal email or cloud storage account may not have the same security protections, retention requirements, or access restrictions as your workplace systems.

Even if you never share the documents with anyone else, transferring them without authorization can create compliance problems.

Always get permission before taking copies of work-related files outside your organization.

If you need portfolio samples, ask whether you can use approved, sanitized examples that don’t contain any confidential information.

Mistake #2: Bringing Old Information to a New Employer

Here’s another scenario: You start a new job and realize you already have a spreadsheet, presentation, or customer list that could save your new team hours of work.

Wouldn’t it make sense to reuse it?

Unfortunately, doing so could expose your new employer to legal problems, too. Confidential information doesn’t automatically become yours to share just because you no longer work for the company that created it.

Instead, use the skills and experience you’ve gained throughout your career without bringing along protected documents or proprietary information. Your knowledge can move with you, but your former job’s confidential files generally cannot.

Mistake #3: Forgetting About Old Access

Changing jobs isn’t the only time employees need to think about access permissions. If you transfer from accounting to marketing, but your account still allows you to open confidential financial records, then you might need to get new account controls.

This is known as access creep, which happens when employees accumulate permissions over time without losing access they no longer need. It can create unnecessary security risks and make it harder for organizations to demonstrate that sensitive information is appropriately protected.

If you notice that you still have access to information you no longer need, notify your supervisor or IT department.

Don’t continue accessing it simply because the system lets you.

How Can You Protect Confidential Information?

Fortunately, protecting company information during a job change doesn’t have to be complicated.

Whether you’re leaving a company, starting a new position, or changing departments, remember:

• Keep company files in approved systems. Don’t transfer confidential documents to personal email, cloud storage, or USB drives without authorization.
• Ask before keeping work samples. Obtain permission before using previous projects in a portfolio.
• Return company devices and records. Follow your employer’s offboarding procedures.
• Report unnecessary access. Tell IT if you can still access information from a previous role.
• Respect confidentiality agreements. Remember that some obligations continue even after your employment ends.

If you discover that you’ve accidentally retained confidential information from a former employer, don’t use or distribute it. Seek guidance through the appropriate legal or compliance contact on how to handle it securely.

Conclusion

The dispute between OpenAI and Apple is a reminder that protecting confidential information doesn’t stop when someone leaves a company. While those allegations remain unresolved, the underlying compliance lesson applies to everyone.

You might spend years creating documents, building customer relationships, or developing projects at work. That experience is valuable, and you can absolutely take your knowledge and professional skills into your next position.

Unfortunately, that doesn’t mean you can take the company’s confidential information along with you.

Keep company information in approved systems, follow offboarding procedures, and ask permission before retaining work-related documents.

Your career experience belongs to you. Make sure the confidential information you’ve been trusted to protect stays where it belongs!
