Proving retaliation in California with a timeline: causation, proximity and Lawson

Retaliation cases are won and lost on dates: who knew what, when, and what happened next. A clean chronology is the backbone of the demand, the opposition to summary judgment and the trial story. This guide covers the standards California courts apply, what timing alone can and cannot prove, and how to build the timeline. It is general information, not legal advice.

Which standard applies

The claim you plead decides the test. The tests differ more than most intake notes suggest.

The 1102.6 standard is the friendliest to employees. In Lawson v. PPG Architectural Finishes, Inc. (2022) 12 Cal.5th 703, the Supreme Court held that Labor Code 1102.6, not McDonnell Douglas, governs 1102.5 claims, and that employees "need not satisfy the McDonnell Douglas test." When the facts support a whistleblower theory, plead it alongside FEHA.

Under FEHA, Harris v. City of Santa Monica (2013) 56 Cal.4th 203 adopted the "substantial motivating factor" standard. If the employer proves it would have made the same decision anyway, the plaintiff loses damages, back pay and reinstatement, but can still get declaratory or injunctive relief and attorney's fees.

The elements, and how the timeline proves each

Yanowitz v. L'Oreal USA, Inc. (2005) 36 Cal.4th 1028 sets the FEHA retaliation prima facie case: the employee engaged in protected activity, the employer subjected the employee to an adverse employment action, and a causal link connects them.

• Protected activity. Complaints about discrimination or harassment, requests for accommodation or CFRA leave, participating in an investigation, reporting a reasonably believed legal violation. The timeline needs the date, the form (email, meeting, hotline) and the recipient.
• Adverse action. Yanowitz asks whether the employer's actions "materially affect the terms, conditions, or privileges of employment," viewed in their totality. A series of acts can qualify together even if one alone would not. Put every act on the timeline, not just the termination: schedule cuts, write-ups, removed accounts, exclusion from meetings, a changed review.
• Causal link. Knowledge plus timing. Fisher v. San Pedro Peninsula Hospital (1989) 214 Cal.App.3d 590 recognized that causation can be inferred from the employer's knowledge of the protected activity and the proximity in time between it and the adverse decision. The timeline has to show who made the decision and when that person learned of the protected activity.

Temporal proximity: what it does and does not do

Proximity carries more weight early in the case than late.

• It can establish the causal link for the prima facie case.
• Under McDonnell Douglas, once the employer gives a legitimate reason, proximity alone is usually not enough to show that reason is pretext. Loggins v. Kaiser Permanente Internat. (2007) 151 Cal.App.4th 1102 is the case defense counsel will cite for that point.
• Under Labor Code 98.6, an adverse action within 90 days of protected activity creates a rebuttable presumption of retaliation.
• Under Labor Code 1102.6, proximity feeds the contributing-factor showing, and the burden then moves to the employer at the clear and convincing level.

So a strong timeline does two jobs: it shows how close the dates are, and it surrounds those dates with the evidence that the stated reason does not hold up.

Evidence that turns proximity into pretext

Look for these and put each on the chronology with its source document:

• A clean or positive record before the protected activity, and criticism that starts after it.
• A change in the employer's stated reason over time (termination letter, agency position statement, discovery responses).
• Discipline that departs from the employer's own policy or progressive discipline steps.
• Comparators who did the same thing and were not disciplined.
• Decision-maker statements about the complaint, the leave or the accommodation.
• An investigation that started only after the protected activity, or that never interviewed the employee's witnesses.

Building the chronology: a checklist

1. List every protected act with date, form, recipient and the document that proves it.
2. List every adverse act with date, decision-maker and document.
3. For each adverse act, record when the decision-maker learned of the protected activity, and how you know.
4. Compute the days between each protected act and each later adverse act.
5. Add performance history before and after, with dates.
6. Add each stated reason, when it was given and where.
7. Mark disputed facts and the witness who can speak to them.
8. Cite the page for every entry, so the chronology can go straight into a brief.

A short example of what the finished entries look like:

Defense arguments the timeline has to answer

Expect the same few arguments in most motions, and build the chronology so each one already has its answer.

• "The decision-maker didn't know." Answer with the date and route of knowledge: the email forwarded to the manager, the HR meeting the manager attended, the leave calendar the manager approved. Without knowledge, proximity proves nothing.
• "The problems started before the complaint." Answer with the full performance history. If earlier criticism exists, show how its tone, frequency or consequences changed after the protected activity.
• "The gap is too long." Months between complaint and termination weaken an inference from timing alone. Fill the gap with the smaller acts in between: changed schedules, lost assignments, a sudden performance plan. Yanowitz lets those acts be read together.
• "Someone else made the call." Map who recommended, who approved and who signed. A biased supervisor who influenced the decision can matter even when someone else signed the letter.
• "Same decision anyway." Under FEHA this limits remedies (Harris); under 1102.6 the employer must prove it by clear and convincing evidence. Comparators and departures from policy are the answer.

Deadlines on retaliation claims

FEHA retaliation follows the CRD process: three years to file, then one year from the right-to-sue notice (FEHA deadlines). A Labor Commissioner complaint under Labor Code 98.7 is due within one year. Labor Code 1102.5 has no limitations period of its own, and courts commonly apply three years under CCP 338(a); calendar it conservatively. Wrongful termination in violation of public policy is two years (CCP 335.1). Labor Code 1102.5 and 98.6 each allow a civil penalty of up to $10,000 per employee per violation.

Building the chronology in PlaintiffStack

PlaintiffStack's employment practice has a Legal chronology page and a case tool of the same name. The tool reads the case's searchable documents and proposes protected activity, adverse actions and the days between them, each citing the page and words it came from. A person accepts or dismisses each entry; nothing lands on the case on its own. Scanned files are not read yet, since there is no OCR. The accepted chronology feeds the pre-litigation demand draft, which waits for review before it goes anywhere. See documents and draft for how citations work.
