An Alameda County, Calif., judge late last week certified a class of an estimated 3,000 Oracle Corp. employees who allege that they were misclassified as exempt and deprived of overtime pay.

Judge Steven Brick’s order certified three subclasses of technical analysts, project managers and quality assurance analysts or developers for Oracle and PeopleSoft, which Oracle bought in 2005. They say Oracle violated provisions of the California Labor Code by failing to pay overtime wages and give them off-duty meal periods.
