Saphie... I think you have helped as much and as appropriately as you can. Get the Director educated about alcoholism... after that, what he does is his call. I think it's a great thing to be concerned for your co-worker. However, don't let that concern harm you and your own recovery, like intention said.
The wheels will turn slowly or quickly, it's up to the company.
Oh, maybe, if you are really so inclined, have the director read the chapter from the Big Book... To the Employer... good stuff there. You can get to it online and print it out for him.
