All too common this day, companies need to cover their arses for every thing. The bigger the company the bigger the potential law suit so less they leave to chance.
You can't assume people use common sense so they have to show that they have communicated and educated staff on all these matter.
I worked on a charter boat where this company had a staff xmas function, not only did I have to brief on boat safety but was also asked to explain that work place guidelines on behaviour ie sexual harassment ect was applicable
