So for some industries, there are set days off as holidays a year. We all know the joke, bank and post office gets the most. The rest get a few. But everyone needs to realize some get NONE! If you work retail or food/beverage you may not get any holidays off, And it is super hard to request those days because everyone wants them. Labor day especially is such a joke to these workers. The laborers have to work harder on their own holiday!
My main point here is, everyone can help with this problem. We know these places stay open because there is money to be made, so simple solution. If you think it should be a holiday for everyone (which many should) then plan your days off properly and DONT GIVE THEM BUISNESS. I know there are exceptions on both side ie: emergencies or people who want to work for extra money. But these are the exception and shouldn't be the norm. You can help your fellow humans by planning a bit ahead for your holidays off. Shop before hand, cook at home.
