Some industries are weekend industries; for Hospitality, Retail and Tourism, Saturday and Sunday are the equivalent of Monday and Tuesday for the 9-5 crowd.
That said, Monday and Tuesday are usually the Saturday and Sunday for these workers. Us “Normies” don’t usually particle in fine dining, clubbing or tourist traps on Monday and Tuesdays.
You are right though, Retail and Hospitality workers do need to get better unions so they can get paid a living wage and aren’t being forced to work 7 days a week for 12 hour shifts.
