How Mediation Confidentiality Works in California Employment Disputes

What California Law Says About Mediation Confidentiality

California has some of the strongest mediation confidentiality protections in the country. Under Evidence Code Sections 1115 through 1128, communications made during mediation are generally confidential and inadmissible in noncriminal proceedings, with limited statutory exceptions (§§ 1120-1128).

This means that statements, admissions, offers, and writings made during mediation are generally inadmissible in noncriminal proceedings under §1119, with limited statutory exceptions. The protections extend beyond the resolution session itself - anything said in preparation for mediation or during mediation consultations is also covered.

For employees and employers dealing with workplace concerns, these protections create an environment where both sides can speak openly about the issues without fear that their words will come back to haunt them.

Key Protections Under California Evidence Code

Section 1119: The Core Confidentiality Rule

Section 1119 is the foundation of California's mediation confidentiality framework. It provides three main protections. First, no evidence of anything said or any admission made during mediation is admissible or subject to discovery. Second, no writing prepared for or during mediation is admissible or subject to discovery. Third, all communications, negotiations, and settlement offers during mediation remain confidential.

These protections apply regardless of whether the mediation results in a settlement. Even if the parties do not reach an agreement, what was said during the process stays confidential.

Section 1120: What Is Not Protected

Section 1120 clarifies that evidence that is otherwise admissible does not become inadmissible simply because it was presented during mediation. For example, if an employer has a personnel file that would be discoverable in litigation, the fact that the file was discussed during mediation does not shield it from discovery.

Section 1121: Mediator Reports

A mediator cannot be compelled to report to the court on the substance of the mediation. The mediator may report only whether a settlement was reached, but not the terms of the settlement unless both parties agree.

Section 1122: Limited Exceptions

There are narrow exceptions to confidentiality. A mediation communication may be disclosed if all parties to the mediation expressly agree in writing, or if the communication is relevant to a claim of mediator misconduct. Also, under Section 1122(a)(3), a written settlement agreement is admissible if it is signed by the parties and states that it is enforceable or binding.

Section 1126: Protections Survive the Mediation

Anything that was inadmissible or confidential before the mediation ends remains so after the mediation concludes. This prevents parties from attempting to use post-mediation proceedings to access what was discussed.

Section 1127: Penalties for Seeking Mediator Testimony

If someone subpoenas a mediator to testify and the court determines the testimony is protected, the court must award reasonable attorneys' fees and costs to the mediator against the party seeking the testimony.

What This Means for Employees

Under California mediation confidentiality law, what a participant says during mediation generally cannot be used against them in court. If you disclose the details of incidents you experienced, those disclosures cannot be introduced as evidence by your employer in a later proceeding.

This protection is designed to encourage honest communication. The idea is that disputes are more likely to be resolved when both sides can be candid without worrying about legal consequences.

However, this also means that promises or offers made by your employer during mediation are generally not enforceable unless they are reduced to a written, signed settlement agreement. Verbal agreements during mediation are enforceable only under specific conditions outlined in Section 1118.

What This Means for Employers

Employers benefit from the same protections. If an employer acknowledges a problem or offers to take corrective action during mediation, those statements are generally inadmissible as evidence in noncriminal proceedings.

This allows employers to engage constructively with employee concerns without the fear that good-faith engagement will be treated as an admission. Many employment attorneys recommend mediation precisely because it allows employers to explore resolution options in a confidential setting.

Section 1129: Informed Consent Requirement

California added Section 1129 to address a gap in the law. Before participating in mediation, an attorney must obtain their client's signature on a disclosure form confirming that the client understands mediation confidentiality. The form must be in the client's preferred language.

This requirement ensures that all participants enter mediation with a clear understanding of the confidentiality rules. If you are considering mediation, ask your attorney to explain the disclosure form and what it means for your case.
