I think it's extremely selfish and exploitative of the retail lobby to keep trying to undermine the work-free sunday, and that has nothing to do with religion to me.
Yup, everyone needs at least one day just to have time to themselves.
I've worked 13:30-22:00 Sunday nights with 8:30am Monday starts straight after, refered to here as "singles shifts" which if you enter your marital status as "single", you get stuck with.
I'd like that got rid of for a start, as you'd think that would be the quietist time you'd have, only the 30-40 customers still queing as your shift is about to end show otherwise.
