I have found from my personal experience that rehabs albeit are GREAT for the user, absolutely do not give a snot about families.
Their primary purpose it to help the patient focus on themselves and learn a sober way to live. And no matter if you use or not, we family members are sick ourselves, and we do affect them if we are not recovering well ourselves. They usually want the patient to stay as far away from psycho codies (like me) so they can get on their feet emotionally.
That being said, if the guy did say all you said he did....he should get his arse whooped by his boss.
