I assume she will lose her job - It's always sad to see a career come to an end with an incident like this. There are normally warning signs along the way and sometimes co-workers can intervene. We have a person we know we have to "manage" when we go out, but fortunately she's a happy drunk and never a problem the next day.
There but by the grace of God go I and and a good few others - although mostly in our twenties!
