"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."
That sounds like the company is trying to do the right thing. Which doesn't surprise me. If - and let me emphasize IF - these disgruntled employees' assertions are true, maybe a few local managers were thwarting the system to lower their expenses? They do have thousands of stores and there are a few weasels in every group.
That is quite possible. My managers are extremely frugal, but they also drill it into you during the hiring process that working off the clock is not acceptable. If anyone asks you to do this, you are to report them. .
I hope the managers at these stores were promptly fired for abusing their employees. Trust me, there are all kinds of ways for the authorities to know if they were skirting around the system.

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.
