You are not legally required to tell your employer you are going to rehab, but you do need to communicate your absence. Understanding your rights under federal law before having any workplace conversation protects your job, your confidentiality, and your recovery.
Your Legal Protections Before You Say Anything
2 federal laws are directly relevant to employees seeking addiction treatment. The Family and Medical Leave Act, or FMLA, allows eligible employees to take up to 12 weeks of unpaid, job-protected leave per year for a serious health condition, which includes substance use disorder and its treatment. The Americans with Disabilities Act, or ADA, prohibits employers from discriminating against employees who have a history of addiction or are currently in recovery, as long as they are not currently using illegal substances.
Before speaking with anyone at your workplace, verify whether your employer is covered by FMLA. Employers with 50 or more employees are required to comply, and you must have worked there for at least 12 months and logged at least 1,250 hours in the past year to qualify. California also provides its own leave protections under the California Family Rights Act, which mirrors FMLA but applies to employers with 5 or more employees, significantly expanding coverage for workers at smaller companies who would not qualify under federal law alone.

What You Are and Are Not Required to Disclose
You are not required to tell your employer you are going to rehab for addiction. You are only required to give sufficient notice of your need for leave and, in most cases, provide a medical certification from a healthcare provider. That certification confirms you need leave for a serious health condition but does not require you to disclose the specific diagnosis to your employer.

Who to Talk to at Your Workplace
In most companies, the conversation about medical leave should begin with Human Resources rather than your direct manager. HR professionals are trained in confidentiality and are legally bound to protect health information shared in the context of a leave request. Going to your manager first is not required and can complicate the situation if your manager does not handle the information appropriately.

How to Frame the Conversation
When you speak with HR, you can use language that focuses on the leave itself rather than the reason. A simple approach is to say that you are experiencing a medical condition that requires residential treatment and that you would like to begin the process of applying for FMLA leave. You do not need to mention addiction, substance use, or rehab by name. Your healthcare provider's certification will satisfy the medical necessity requirement without revealing your diagnosis to your employer.
Planning Your Leave Logistics Before the Conversation
Prepare 3 practical details before speaking with HR: the approximate start date of treatment, the estimated duration, and a handover plan for your responsibilities. Having these details ready demonstrates professionalism and reduces the friction that sometimes arises when a leave request feels abrupt. Most residential programs last between 30 and 90 days, and HR departments in FMLA-covered companies process these requests routinely.
Managing Your Career During and After Treatment
Your employer cannot fire you for taking FMLA leave, and the ADA prohibits discrimination against employees who have completed a rehabilitation program. However, returning to work after treatment requires navigating workplace relationships thoughtfully. You are not obligated to explain where you were. You are entitled to return to your same position or an equivalent one with the same pay and benefits.
If you are concerned about your employer's response, consider consulting with an employment attorney before having the conversation. Many attorneys offer a free initial consultation and can help you understand your protections in your specific state, since some states provide additional leave rights beyond federal minimums. California employees also have access to State Disability Insurance through the Employment Development Department, which can provide partial wage replacement during a leave for medical treatment, including treatment for substance use disorder. Filing an SDI claim in parallel with your FMLA request can reduce the financial impact of taking unpaid leave for treatment, and California's SDI program pays approximately 60 to 70 percent of weekly wages for eligible recipients during a qualifying medical leave.
