You took FMLA leave, came back to work, and something was different. Maybe your position changed, your hours were cut, or your manager suddenly found performance problems that didn’t exist before. Or maybe you never made it to leave at all because your employer found ways to discourage, delay, or deny your request. Either situation can involve an FMLA violation, but the legal theory behind each one is different. That distinction shapes everything: the evidence you need, the burden of proof, and what you can recover.
At Weiler Law PLLC, we’ve represented Phoenix employees in FMLA matters for more than 14 years. Attorney Amanda Kuklinski focuses on FMLA claims, employment discrimination, wrongful termination, and hostile work environment cases. One of the most common questions employees bring to us is whether what happened to them was interference, retaliation, or both. Understanding which category fits the facts changes the legal path forward.
Two Types of FMLA Claims, One Critical Difference
The Family and Medical Leave Act creates two distinct causes of action. They overlap in some situations, but courts analyze them differently, and treating them as interchangeable is a mistake.
FMLA interference, defined under 29 U.S.C. 2615(a)(1), prohibits employers from denying, restraining, or otherwise interfering with an employee’s exercise of FMLA rights. The defining feature is that intent doesn’t matter. If the employer’s conduct resulted in the denial or obstruction of protected leave rights, liability can exist regardless of whether the violation was deliberate. FMLA retaliation is different: it prohibits an adverse employment action taken because an employee exercised FMLA rights, and it does require proof of employer motive. The employee must show the employer acted against them because of the protected activity, not just that the employer acted against them.
A second structural difference: interference requires that the employee was actually prevented from or hindered in taking protected leave. A retaliation claim can be brought even when the employee took the full leave without obstruction, if the employer punished them for it afterward.
What FMLA Interference Looks Like in Practice
Interference doesn’t always look like a flat denial. It can appear at any stage of the leave process.
Before leave, it can include providing incorrect eligibility information, discouraging the request with comments about career consequences, or simply failing to inform an employee that their condition may qualify for protection. During leave, it can include sending work demands, contacting the employee repeatedly about ongoing projects, or pressuring them to return early. After leave, the most common form is failing to restore the employee to the same position or an equivalent one in terms of pay, benefits, and responsibilities. Reinstatement rights under FMLA are concrete, not aspirational.
One form of interference employees frequently miss is the no-fault attendance policy trap. Some employers track absences using a point system and count FMLA absences the same as unexcused ones. Under 29 CFR 825.220 and the Department of Labor’s Fact Sheet 77B, that practice is explicitly prohibited. If an employer counts FMLA-protected absences toward discipline thresholds, that’s interference, regardless of whether the employer calls it neutral policy.
What FMLA Retaliation Looks Like in Practice
A retaliation claim rests on three elements: the employee engaged in FMLA-protected activity, the employer took an adverse employment action, and there’s a causal connection between the two. Protected activity includes requesting leave, submitting medical certification for a serious health condition, or simply asking questions about FMLA rights.
The adverse action doesn’t have to be termination. Common retaliation patterns include demotion or pay cuts framed as restructuring, sudden negative performance reviews citing attendance or “commitment” problems, increased scrutiny following a leave request, and schedule changes that make the position effectively untenable. When these changes follow leave closely in time, that temporal proximity is meaningful evidence.
Arizona employees have an advantage worth knowing. The Ninth Circuit, which covers Arizona, has historically applied the motivating factor causation standard to FMLA retaliation claims. Under that standard, the employee’s protected activity need only be a motivating factor in the employer’s adverse action, not the sole cause and not the but-for cause. This area of law continues to evolve across circuits, but the motivating factor approach remains the framework applied in the Ninth Circuit. Some circuits, including the Eleventh, apply the stricter but-for standard, which requires showing the adverse action wouldn’t have occurred at all without the protected activity.
Retaliation cases often proceed through the McDonnell Douglas burden-shifting framework: the employee establishes a prima facie case, the employer offers a legitimate nondiscriminatory reason, and the employee then demonstrates that reason is pretextual. Temporal proximity between the protected activity and the adverse action is a key tool for raising the inference of causation at the first step.
When Both Claims Apply to the Same Situation
Interference and retaliation aren’t mutually exclusive. The same set of facts can give rise to both claims simultaneously.
Consider an employer who denies a leave request, disciplines the employee for absences taken during what should have been protected leave, then terminates the employee after they file a complaint. The denial is interference. The termination following the complaint is retaliation. Both claims exist, both have different elements, and pursuing both often produces the strongest case. Whether the harmful action occurred before the leave, during it, or after it shapes the theory. When all of it happened, all of it is on the table.
Arizona Protections That Work Alongside FMLA
Federal FMLA isn’t the only protection available to Arizona employees. The Arizona Fair Wages and Healthy Families Act provides paid sick leave independent of FMLA. Employees accrue one hour of paid sick leave for every 30 hours worked, up to 40 hours per year at employers with 15 or more workers, and up to 24 hours per year at smaller employers. In some situations, FMLA leave and Arizona paid sick leave run concurrently, meaning the same absence can be covered by both.
Interference with Arizona paid sick leave rights is a separate violation from FMLA interference, which matters when FMLA coverage doesn’t apply. An employee who doesn’t qualify for FMLA may still have a state law claim, and one who qualifies for both may have violations under both frameworks to pursue. Filing deadlines are strict: FMLA claims must generally be filed within two years of the violation, or three years for willful violations. Waiting reduces the ability to preserve documentation, locate witnesses, and meet the statutory requirements.
Steps Arizona Employees Should Take If They Suspect a Violation
The evidence that supports an FMLA interference or retaliation claim is almost entirely in the employee’s control to preserve, and it disappears faster than most people expect.
Start building your documentation now:
- Written leave requests and responses: Save every email, text, or written communication related to the FMLA request, approval, denial, or any modification.
- Employer communications before, during, and after leave: Preserve messages about workload, performance, scheduling, or team changes that arrived while you were on leave or shortly after you returned.
- Performance reviews and disciplinary records: Compare reviews from before the leave request to those issued after, and note any changes in tone, content, or rating.
- Contemporaneous notes: After any verbal conversation about your leave, write down what was said, when, where, and who was present. Date every note.
One important point: employees don’t need to use the word “FMLA” to trigger their employer’s obligations. Once an employer has notice that leave may be needed for a qualifying reason such as a serious health condition, the employer has a legal duty to inform the employee of FMLA eligibility and designate the leave accordingly. Failing to do that is itself interference.
FMLA claims can be filed with the DOL Wage and Hour Division or through a private civil lawsuit in federal court. Both paths are available, and neither must be exhausted before pursuing the other. Available remedies include back pay, front pay, lost benefits, liquidated damages (which can double the back pay award in cases of willful violations), and attorney’s fees.
