Business news in brief

Hershey Entertainment & Resorts Co., which operates Hersheypark, said Friday that its on-site card-payment system was hacked and consumers should be vigilant about unauthorized charges on their bills. The company warned that people who used credit cards at Hersheypark and other properties between Feb. 14 and June 2 should monitor statements. Many of the credit cards used after May 9 "were likely not affected," a Hershey Entertainment spokeswoman said. The company's properties include the Hotel Hershey and the Hershey Lodge. The company said it did not believe the online ticketing operations related to Hersheypark or the Giant Center were compromised. But people who bought concessions at the venues could have been affected. - Bob Fernandez

The U.S. Equal Employment Opportunity Commission sued Crothall Services Group Inc. in U.S. District Court in Philadelphia on Thursday, alleging failing to keep proper employment records. The suit said Crothall, a nationwide janitorial and facilities management services company based in Wayne, routinely assessed applicants' criminal backgrounds in making hiring decisions. Federal law requires employers to keep records that show whether the use of criminal background checks or any other selection test ends up causing discrimination in the hiring process. - Jane M.
