As a retail/hospitality worker that works shifts, I don’t like the idea of one of my days off per week being mandated to appease the increasingly irrelevant/tedious religious/traditionalist lobby. Especially so when everything is closed on that day and I can not use it as productively as I may wish subsequently. Sunday trading is already inconvenient enough, because you finish your shift and everything is closed (we need to do our shopping too), and it funnels all your customers into a narrow time period and they are all gobsmacked and complaining that it’s busy or that you’re closing early. Retail establishments should be able to choose their own opening hours and lengths on a Sunday in line with demand.
For those who wish to stay in on a Sunday, abstain from retail and pretend it’s 1947, that option exists.
