Each year the staff choose what they'd like to do for Christmas and this year they have opted for a Chinese Meal out followed by a trip to the Christmas Ice Rink for some Ice Skating. As their employer I will be paying for the whole evening which will include drinks at dinner. I certainly wouldn't allow anyone to go over board on the alcohol and then skate but I am a little concerned that if someone does fall over and hurt themselves that I would be liable if I'd been to one to buy them a glass of wine or two.
Would it be ethical to get the staff to sign a disclaimer prior to the Christmas do pointing out that they are responsible for their own safety? If so does anyone have any suggestions on the best wording to use?
