Lots of people work holidays. I met an architect and his office was open 24/7/365. The owner was tired of deciding holidays, religious days, who should get off for a piano recital, sick days, so just declared all days work days and the employees worked when they wanted and didn’t work when they didn’t want to. My brother’s girlfriend is an attorney and has a lot of overseas clients. She worked thanksgiving because her clients needed something.
