Five Things California Employers Need to Understand About At-Will Employment
California is technically an at-will employment state. But practically speaking, that designation comes with so many asterisks that employers who treat at-will as a blank check to terminate anyone at any time are setting themselves up for costly litigation.
Here are five things every California employer needs to understand about the at-will doctrine:
1. At-Will Is the Starting Presumption — Not a Guarantee
California Labor Code section 2922 presumes that employment with no specified term “may be terminated at the will of either party on notice to the other.” That is the legal baseline. But it is just a starting point. The moment an employer creates an express or implied contract — through an offer letter, a handbook provision, or even verbal assurances from a manager — the at-will relationship can be modified or eliminated entirely. Employers need to actively preserve at-will status rather than assume it exists by default.
2. Employment Contracts Change the Rules Entirely
If you enter into a written employment contract for a specified term, at-will termination no longer applies in the traditional sense. Under Labor Code sections 2924 and 2925, a contract employee can only be terminated mid-term for a willful breach of duties, habitual neglect, or continued incapacity to perform. Similarly, the employee may only walk away for a willful or permanent breach by the employer. This is a very different standard than the at-will baseline — and employers who use employment contracts without understanding this distinction can find themselves facing breach of contract claims when they attempt to terminate someone they assumed was at-will.
3. Protected Categories and Activities Narrow At-Will Significantly
Even where at-will status exists, employers can terminate for any reason — or no reason at all. That is actually the point of at-will employment. What employers cannot do is terminate for an unlawful reason. California law prohibits adverse employment actions based on a lengthy and expanding list of protected categories — race, age, disability, gender identity, sexual orientation, military status, and more — as well as a growing list of protected activities including whistleblowing, jury duty, wage discussions, and even off-duty cannabis use. The distinction matters: you do not need a reason to terminate an at-will employee, but if the reason you do have turns out to be an unlawful one, you are exposed.
4. The 90-Day Retaliation Trap Under SB 497
This is where many well-intentioned employers get blindsided. SB 497, commonly referred to during its passage as the Equal Pay and Anti-Retaliation Protection Act, was signed by Governor Newsom on October 8, 2023, and took effect January 1, 2024, amending Labor Code sections 98.6, 1102.5, and 1197.5. It creates a rebuttable presumption of retaliation any time an employer takes an adverse action against an employee within 90 days of that employee engaging in protected activity.
Those three code sections cover a wide swath of common workplace situations:
- § 98.6 — protects employees who report wage and hour violations
- § 1102.5 — the whistleblower statute, protecting employees who report reasonably believed legal violations to a government agency
- § 1197.5 — protects employees who discuss wages, ask about a coworker’s pay, or invoke their rights under California’s Equal Pay Act
Here is the practical trap: before SB 497, employees had to prove three things — protected activity, an adverse action, and a causal connection between the two. Now, if the adverse action happens within 90 days, the causal connection is presumed. The burden immediately shifts to the employer to prove the action was for a legitimate, non-retaliatory reason. Fail to do that, and the employer faces civil penalties of up to $10,000 per employee per violation — paid directly to the employee, not the state.
The real-world scenario that catches employers off guard: a manager has been meaning to address a performance issue for weeks, the employee files a wage complaint, and the manager finally acts. Even if the discipline was completely justified, the timing alone now puts the employer on defense in a retaliation claim. Documentation of performance issues before any complaint arises is no longer just good HR practice — it is your legal defense.
5. You Must Actively and Consistently Communicate At-Will Status
At-will status is not something you establish once and forget. It needs to be reinforced at multiple touchpoints: the offer letter, the employee handbook, onboarding acknowledgments, and any time the handbook is updated. The at-will clause in your handbook should specify that it can only be modified in writing signed by the owner, CEO, or president — not any manager. Verbal assurances by managers that an employee’s job is “secure” or that they will “always have a place here” can create implied contract claims that undermine even the most carefully drafted written policies. Train your managers on this. Their words carry legal weight whether they realize it or not.
The bottom line: California at-will employment is real, but it is fragile and narrowing. Employers who invest in clear policies, consistent documentation, and proactive manager training are far better positioned when a termination is challenged — and far less likely to hand a plaintiff’s attorney an easy 90-day retaliation argument.
