This actually applies every single week....to Sundays. Without any blue laws, employers are totally empowered to demand workers work on Sunday, even though, theoretically, it is supposed to be "voluntary" and the law requires employers to respect employees' religious Sabbath. They do not.
People wonder why so few young people go to church. Entry level jobs are most often in the service industry--where almost always, people are required...to work on the Lord's day. Very sad, and, wrong.
You’ll get no argument from me on that. I do not shop on Sundays unless I have to drive further than the tank of gas I filled up on Saturday will take me. Then I will buy gas.
