Why? Cause shops are open on sunday? Having no workers rights makes that a lot easier
Yes. Shops being closed on Sundays is a major PITA. I have 2 days off a week. So I have to buy groceries in overcrowded shops in the evening or in overcrowded shops on Saturdays. Or I drive across the border and buy in Luxemburg, on Sundays. So the VAT I am creating stays in another country. Which is just plain stupid.
Also: workers' rights and shops being open on Sundays aren't mutually exclusive.
