Another of my usual random subjects, now 'appearing' as a thread following a discussion with someone else of this site, on the subject.
Basically, in the United Kingdom before Thatcher, most trading on a Sunday was prohibited in law.
During her premiership this was changed, although due to (I believe) heavy resistance from dominant Anglian church groups, it was not completely removed, the original proposals to scrap all trading restrictions watered down to a situation where businesses over a certain size (with some exemptions, such as railway stations, airports, theatres, cinemas, etc) are only permitted to trade for a total of six hours on a Sunday, which must fall between 1000 and 1800.
My personal opinion, is that such legislation is outdated and unecessary. I do not believe that the feelings of a particular religion or domination should be allowed to dominate law affecting the whole country - especially, as so few people in the United Kingdom attend any place of worship more than once a year, statistically.
Indeed, if we were to enact restrictions on trading to please every religion and denomination, then I imagine there would be no trading, as some entity, somewhere, would regard at least one day as sacred, and thus deemed "wrong" to trade on.
The continuation of this legislation is also detrimental to the increasing number of people who work five, five and a half, or six day weeks. Why should one be forced to shop during particular hours on the only day when it is possible?
