As an employee, when I had a retail job I used to put in a request to work on Christmas Day. My family celebrates together on Christmas Eve, so Christmas Day I would be able to work a shift making time and a half on what would be an easy work day since business was light that day. Plus it allowed other employees who celebrated on Christmas Day to be with their families.
Good point .the way our family celebrated, Christmas Eve thru late Christmas am was it .by noon, it was almost another day.
