Sprint (NYSE: S) just can’t get a break. A fresh class-action lawsuit is accusing the carrier of cheating thousands of retail store employees out of sales commissions due to a computer snafu, The Kansas City Star reports. A Sprint spokesman told us the matter is still very early in the legal process, but added: “We’re disappointed with the decision to certify the class, particularly because Sprint is committed to providing its employees with the compensation to which they are entitled.” The lawsuit, which was originally filed last February in U.S. District Court in Kansas, was certified as a class-action matter on Monday. The court also ordered Sprint to submit a list of all potentially affected sales clerks by Dec. 22. The lawsuit alleges that Sprint’s computer system experienced glitches and left some sales unreported, which resulted in numerous unpaid commissions. The employees estimate they lost out on $100 to $500 a month, amounting to as much as six figures each. Lawyers representing the worker put the total damages at more than $5 million.
