The Employer’s Playbook: Common Defense Strategies and How They Are Challenged
Every employer that defends an employment case uses a recognizable set of strategies. Understanding those strategies — and knowing how a plaintiff’s attorney responds to each — removes the mystery from the process and explains why the employer’s version of events is not always the final word.
My experience includes both plaintiff-side wage-and-hour work and employer-side employment litigation. I participated in defending employment cases. The strategies are not secret, and they are not infinite. They are a finite set of arguments, deployed in predictable patterns, designed to accomplish specific objectives. Understanding them does not guarantee that the plaintiff prevails. But it eliminates the informational asymmetry that makes the employer’s defense seem more formidable than it is.
What follows is a description of the most common defense strategies in California employment cases, and the ways in which plaintiff’s attorneys respond to each.
“The termination was for legitimate business reasons”
This is the default defense in every wrongful termination case. The employer identifies a reason — performance, misconduct, reorganization, position elimination, insubordination, cultural fit — and presents it as the complete explanation for the termination.
How it is challenged. The plaintiff does not need to prove that the stated reason is false. The plaintiff needs to prove that it is pretextual — that the stated reason is not the real reason, or that it is not sufficient to explain the decision.
Pretext is established through evidence that the reason does not hold up under scrutiny. Were the performance concerns documented before the protected event, or did they appear afterward? Were comparable employees with similar records treated the same way? Is the employer’s explanation consistent across time and across witnesses, or does it shift? Did the employer follow its own policies and procedures, or did it deviate from them? Is the reason objectively supported by the evidence — the performance reviews, the metrics, the documentary record — or is it a post hoc characterization?
The strength of the defense depends entirely on the quality of the documentation. An employer with a genuine, well-documented performance history that predates the protected event is in a strong position. An employer whose documentation materializes after the complaint, whose reasons shift between the termination meeting and the deposition, and whose treatment of the plaintiff diverges from its treatment of comparably situated employees is not.
“The decision-maker did not know about the protected activity”
The employer argues that the person who made the termination decision did not know the employee had filed a complaint, requested accommodation, taken leave, or engaged in other protected activity. If the decision-maker was unaware, the argument goes, the decision could not have been motivated by the protected activity.
How it is challenged. In many organizations, the person who signs the termination paperwork is not the person who initiated or drove the decision. The “cat’s paw” theory — named for the Aesop fable — holds the employer liable when a biased individual (a supervisor who knew about the protected activity and harbored animus) influenced the decision-maker, even if the decision-maker was personally neutral.
The challenge focuses on the chain of information: who recommended the termination? What information did they provide to the decision-maker? Was the biased supervisor’s input a factor in the decision? Did the decision-maker conduct an independent investigation, or did they rely on the biased individual’s characterization of the employee?
If the supervisor who retaliated provided the performance assessment that the decision-maker relied on, the bias is laundered through the organizational structure but it still infected the decision. Courts and juries recognize this dynamic.
“The same person hired and fired the employee”
The “same actor” inference: if the same person who hired the employee also fired the employee, and the protected characteristic was known at both times, the inference of discrimination is weakened — because the same person who was willing to hire a member of the protected class presumably would not fire them for belonging to it.
How it is challenged. The inference is not a presumption, and it is not dispositive. It is one factor among many, and it can be overcome by evidence that circumstances changed between the hire and the termination.
The most common rebuttal: the protected activity occurred after the hire. An employer that hired a woman willingly and fired her after she filed a harassment complaint is not shielded by the same-actor inference — the relevant change is not the employee’s gender (which was constant) but the complaint (which was new). Similarly, an employer that hired a fifty-year-old employee and fired them at fifty-five may have developed age-based animus during the intervening period, as the employee aged or as the employer’s workforce strategy shifted.
The same-actor inference is a defense talking point, not a legal bar. Strong circumstantial evidence of discrimination or retaliation overcomes it.
“The employee’s own misconduct justifies the outcome”
The “after-acquired evidence” doctrine: during litigation, the employer discovers that the employee engaged in misconduct — falsifying a resume, stealing company property, violating a policy — that the employer did not know about at the time of termination but that would have justified the termination had it been known.
How it is challenged. The California Supreme Court addressed this in Cotran v. Rollins Hudig Hall International and related cases. After-acquired evidence does not eliminate the employee’s claim. It may limit remedies — specifically, it may cut off the employee’s right to reinstatement and may limit back pay to the period between the wrongful termination and the date the employer discovered the misconduct.
But the claim survives. The employer terminated the employee for an unlawful reason. The fact that a lawful reason existed (but was not known) does not retroactively legitimize the termination. The employee can still recover damages for the period during which the wrongful conduct was the operative cause of the harm.
The practical significance: employers sometimes conduct aggressive post-termination investigations of former employees, searching for misconduct that can be used to limit liability. The doctrine permits the employer to use what it finds, but only to limit remedies — not to escape liability entirely.
“The employee did not mitigate damages”
The employer argues that the employee failed to make reasonable efforts to find new employment after the termination, and that the damages should be reduced because the employee could have earned income that would offset the back pay claim.
How it is challenged. The duty to mitigate is real, but it is limited. The employee must make reasonable efforts to find comparable employment. “Comparable” means similar in terms of compensation, responsibilities, and working conditions. The employee is not required to accept a position that is significantly inferior, that is in a different field, or that would require relocation.
The burden of proving failure to mitigate is on the employer. The employer must show not only that the employee did not make reasonable efforts but also that comparable employment was available and that the employee would have obtained it with reasonable effort.
In practice, an employee who can show a documented job search — applications submitted, interviews attended, networking conducted — has satisfied the mitigation duty. An employee who took several months to begin searching may face scrutiny, but a reasonable period to recover from the emotional impact of a wrongful termination is generally not held against the plaintiff.
“The employee was not meeting legitimate expectations”
In discrimination cases, the employer argues that the employee was not performing the job satisfactorily — undermining the prima facie case, which requires the employee to show they were qualified for the position.
How it is challenged. The question is not whether the employee was perfect. It is whether the employee was meeting the employer’s legitimate expectations at the time of the adverse action. Performance that was acceptable before the protected event, and that became unacceptable only after, raises the inference of pretext.
The challenge also focuses on whether the expectations were legitimate or manufactured. An employer that changes the employee’s performance standards, increases the workload, or assigns impossible tasks after the protected event — and then cites the employee’s failure to meet the new standards — has not demonstrated that the employee was underperforming. It has demonstrated that the employer engineered a failure.
Why this matters
Understanding the employer’s playbook does not make the case easy. It makes it legible. An employee who knows what the employer will argue — and how those arguments are tested — can evaluate their own case with greater clarity and participate in their defense with greater confidence.
Every defense strategy has a counter. Every stated reason is subject to scrutiny. Every inference the employer draws can be challenged with evidence that tells a different story. The employer’s version of events is the beginning of the conversation, not the end — and the legal system exists to determine which version the evidence actually supports.
If your employer has offered a reason for your termination and you believe the real reason was something the law prohibits, the stated reason is not the final word. It is a claim — and like all claims, it must be tested against the evidence. Understanding how employers defend these cases is the first step in understanding how they are won.
