I think PalenQ only meant supermarket workers - who are unionized - get more pay on Sundays. Other retail does not have that protection.

Even supermarkets here that are non-unionized like Meijer and the local Spartan store pay a premium for Sunday work - at least amongst the regular fulltime staff.

But no most retail may not unless unionized - a fraction

I wonder if Wal-Mart pays a Sunday premium?
