When Chick-Fil-A first opened its first restaurant, the owner and founder Mr. Truett insisted that Chick-Fil-A close its premises on Sundays to allow its employees to rest, and worship if they so desired. He himself had formerly worked at 24-hour restaurants that opened seven days a week, and he knew how taxing that could be on the employees. So, he made it apparent that any Chick-Fil-A employee would be given Sunday off to rest and recuperate ready for the coming week. It is estimated that by closing on a Sunday, Chick-Fil-A loses about $1 Billion a year in potential income. Mr. Truett doesn't mind, though. He believes that Sunday is supposed to be a day of rest, and so for Chick-Fil-A employees, it is.
