German law requires retail stores to close on Sundays and Christian holidays to give employees days of rest. Supermarket chain Tegut has gotten around this by fully automating its stores, and it gets 25 percent to 30 percent of its sales on Sundays. But a court ruled that the supermarket must give its robots Sundays off as well. A shop workers' union filed suit to force the stores to close, saying it fears the company's success could undermine support for the nation's blue laws.
