Refuse collection workers in Colchester have been banned from wearing Christmas hats or anything Christmassy on the grounds of health and safety. The council have stated drivers and other road users could be distracted.
There is no health and safety legislation that prevents refuse collectors wearing Santa hats or entering the festive spirit with other modest decorations. Excessive displays which might impede the driver's vision or cause a distraction are another matter, but that doesn't seem to be the case here. Being sensible about health and safety can still allow everyone to have some fun too!
