"Also the computer system locks you out when you clock out and you have to take a 30 minute lunch break. It will not let you clock back in until the 30 minutes has passed."
My wife works at Walmart and was contacted by the law firm handling the case. She refused to be any part of it. She explained that it was probably a few bad managers and some current and former workers looking for some free money. These workers apparently worked through a 15 minute break or two. It was hteir responsiblity to take their breaks and they chose not to.
Usually it seems that one is paid for 15 minute breaks whether they take them or not. Working through lunch breaks have to be paid if the employee for the most part is doing his job duties.
If someone is needed to do something during their 15 minute break at our store they get to start the entire break over again.
If they only had 1-2 minutes left they still get 15 minutes more.
