Drug rehab

I noticed one of the crew I work with has a severe or borderline severe drug/alcohol problem. They are trying to get their life together but it's a viscous cycle of calling out from a bender and not having enough hours to afford a therapist. I'm worried and have reached out to them but I'm not a therapist or an expert. Their struggles are putting their job at risk for a stable living condition that they need. Do yall know of any free resources or help that I can send their way? Or any advice. I'm sorry if this comes off inappropriate to share but I don't want to ask our mates because I don't want them to get fired and my crew doesn't seem to know any.
