You will likely need to take a medical break from your job during the first few phases of your rehab program. It’s important that you prioritize your health during this time and the only way to do that effectively is to devote a large chunk of your days to recovery.
That being said, you will be able to return to your job after you complete your detox and the inpatient portion of your rehabilitation. Once you transition to a sober living home or into an aftercare program, you will be able to continue working while you heal so that you can get used to maintaining your sobriety in your daily life.
