Your Boss Does Not Get to Know Your Diagnosis
“Just tell me what’s wrong, and I’ll approve the leave.”
Managers say some version of that every day. It sounds reasonable.
It isn’t.
Under the federal Family and Medical Leave Act (FMLA), an employer’s certification form can ask your doctor for medical facts about your condition. In California, the California Family Rights Act (CFRA) controls, and it is stricter.
Under Gov’t Code § 12945.2 and the CFRA regulations, Cal. Code Regs., tit. 2, § 11091, your employer can require a certification from your health care provider, but it cannot require your diagnosis. You can choose to share it; they cannot make it the price of the leave.
What the certification covers: when the condition started, how long it is likely to last, and a statement that you cannot perform your job.
Here is how it sounds at work:
What they say: “HR needs the diagnosis for the file.”
What it means: The file needs a certification, not a diagnosis.
What they say: “Just fill out the federal form.”
What it means: In California, the federal form’s questions about medical facts should not be required.
What they say: “No diagnosis, no leave.”
What it means: That is a condition CFRA does not allow.
CFRA covers employers with five or more employees, which reaches far more small businesses than the FMLA’s 50-employee threshold.
Whether a request crossed the line depends on how it was made, what form was used, and what happened when you declined, because a manager’s curiosity is different from a denial.
Your diagnosis is yours. Hand over the certification, not your medical file.
