In January 2020 the president of the German retail association HDE called for a change to the Basic Law to make Sunday opening easier. The services union ver.di answered: Wir lehnen eine Grundgesetzänderung strikt ab. We strictly reject a change to the Basic Law. A spokesman for the Catholic bishops said that the alternation of work and rest belongs to human life. In July 2026 the e-commerce association bevh, the HDE and the chambers of commerce, DIHK, pressed again for more Sunday opening. In a representative YouGov poll, 43 percent favored more frequent Sunday opening and 50 percent were against. About a year earlier, 34 percent had been in favor and 59 percent against. For ver.di, Sunday is der einzige verlässlich planbare freie Tag, the only free day that can be reliably planned.
