A work colleague might have a problem
Over the last year a work colleague has been acting strange in his behaviour, as in sneaking about or always asking where I will be at different times of the day and I have now found evidence that he is drinking while in work ( we work outside on landscaping) he hides half full cans of beer to consume in places he thinks nobody will find them and you always have the feeling after a while he wants to get rid of you. He is known to like a drink but I have smelled it on him and people treat it as a sort of joke i.e talking about indifferently like it's fine by passing it off as thats what people do i.e drinking to excess or saying things like piss head about him, but he obviously has a bigger problems than people think. I already know its not normal to be drinking at all times of the day while in work but is it normal to continue to pretend that there is nothing wrong, I'm not sure what to do.
