Confidentiality at Work and What Follows You Out the Door

What follows is an argument about confidential information after employment, and about where the received version of it stops being true.

The categories of information

Legal systems typically distinguish between genuine trade secrets, ordinary confidential information and the general skill an employee acquires. Trade secrets are usually protected after employment ends, often without any need for an express clause. Ordinary confidential information is generally protected during employment and afterwards only where a contract says so clearly.

General skill, knowledge and experience belong to the individual, since employment would otherwise permanently reduce a person's employability. The boundaries between these categories are drawn differently across jurisdictions and are frequently the subject of litigation.

What counts as a trade secret

The usual requirements are that the information is genuinely secret, has commercial value because of that secrecy, and has been protected accordingly. Information published on a website or shared freely with customers rarely satisfies those requirements. Employers who label everything confidential without differentiation weaken their position when they need to identify what truly matters.

On the face of the agreement, access controls, marking and specific training are the practical steps that demonstrate genuine protection. The statutory definitions differ between countries, and several have introduced dedicated trade secrets legislation in recent years.

The memory problem

An employee cannot unlearn what they know, which makes enforcement against remembered information genuinely difficult. The distinction usually drawn is between deliberately memorising specific data and simply carrying accumulated professional understanding. Reciting a client list from memory is treated very differently from knowing generally how an industry works.

This is why non-solicitation clauses exist, since they address the use of relationships without requiring proof about information. Employers combining confidentiality obligations with targeted restrictions are addressing the practical rather than the theoretical problem.

Taking documents

Copying files, forwarding emails to personal accounts or taking documents on departure is treated very seriously in most systems. It is usually a clear breach of contract and may engage separate obligations relating to data protection and computer misuse. Employers commonly run forensic checks on departing employees in sensitive roles, and such checks find this behaviour routinely.

Where a dispute goes formal, the strength of an employer's position increases substantially where documents were taken, regardless of what was later done with them.

Returning everything and keeping nothing is the only approach that avoids this entire category of exposure.

Continuing obligations

Confidentiality clauses are usually drafted to survive termination, and survival clauses list them explicitly for that reason. Duties may also continue under general law relating to confidence, independently of what the contract provides.

Obligations owed to clients, patients or regulated parties frequently continue and are enforced through professional regimes. Where regulated professions are involved, the professional obligations often exceed the contractual ones. Reading the survival clause on departure clarifies exactly which obligations you are carrying forward.

Reporting wrongdoing

Most systems provide protection for disclosures about wrongdoing, and confidentiality clauses generally cannot lawfully prevent them. The scope of protection, the categories of wrongdoing and the required recipients differ substantially between jurisdictions.

Agreements attempting to prevent protected disclosures have attracted regulatory and legislative attention in several countries. Anyone considering such a disclosure should take advice first, because the protection depends on following the applicable route. Getting this wrong can remove protection entirely, which is why it is not a decision to take from general reading.

The takeaway

Take your experience and leave the documents, which is the line that keeps almost everyone out of trouble. General information, not legal advice.

Understanding a process is not the same as being represented in it.
