It is one of those questions that can be viewed in so many ways.
To say Museums, science parks, garden centers etc are surely favourable places to take your family for a day out rather than shopping also means there are staff who are working on a Sunday whilst their family are at home to keep such places open , so Sunday working will apply to somebody somewhere at any one time.
I have a friend who chose to work Sundays at Morrison's as she could cover school duties mid week and use her parents less for child care, hubby took over on the weekends she was on duty. It didn't seem to bother them as he bonded well with the kids as he became a dad who cooked, played and entertained his kids. Other dad's could work Monday to Friday and go to the pub, football, play golf on their Sunday off.
My daughter worked at Morrison's and Birmingham Airport when she was a student and was very glad of the hours she was given, including Sunday working , to pay her way through uni.
If you go on holiday do you say I have a principal that I will not fly on a Sunday as I don't agree with people having to work Sundays. If you travel on a Sunday do you say I refuse to fill my car up as it's Sunday and I don't believe the petrol station attendant should be home with her family.
Someone is always working Sundays somewhere . Some are greatful for the chance to earn a wage.
I am not trying to argue the point, just adding another view.
