(Sorry for grammatical errors) My job put out a sign on Sunday to let customers, and employees, know that we’re closing at 8pm for Memorial Day. We all came in on Monday doing our thing when suddenly we got a surge of customers showing up due to a car meet that was happening right in front of the store. I’m guessing the boss saw them through the cameras and called one of the workers at the last minute to let everyone know that we will be closing at 9pm instead. A lot of the coworkers, including myself, felt very bummed about it. Our deli department was more pissed because they already cleaned all the equipment and now they had to stay an extra hour. One of my co workers didn’t wanna stay the extra hour so he left exactly at 8. Another co worker had to tell her husband (he was waiting for her outside) that she has to get off at 9 and he got really mad. And since I already finished my shift I clocked out because there’s no way in hell am I staying and miss out on the cookout my family was doing. From what I heard, that extra hour was fruitless because little to no customers showed up, guessing they saw the sign and didn’t bother shopping. Anyone know if this is legal? Im at Illinois if that helps answering the question.
