The Sabbath laws (alternatively known as "blue laws") were a series of laws designed to prevent people from working on the Sabbath, commonly known as Sunday, to respect the Abrahamic God's day of rest. They, like most laws enforced by the morality department, disproportionately affected working-class people and favoured the upper class. One of the best examples of this was the fact that taxis used by the public to get around were not allowed to work on Sunday, but private chauffeurs of the wealthy were. Beyond preventing many forms of work, they also prevented people from doing certain leisure activities that could be interpreted as work. Similar to the taxi driver–chauffeur contradiction, ball games for children in public on Sundays but still allowing for games of golf at private clubs. Such contradictions led people to believe that these laws were put in place to prevent working-class people from consorting with each other, to keep them separate and easy to manage.
