A federal judge in New York has conditionally certified a nationwide class action against MetLife over allegations it withheld more than $50 million in earned overtime pay from certain claims specialists since 2013.

The class includes hundreds of long-term disability claims specialists whose jobs were reclassified in 2013 after which they were deemed “exempt” and denied overtime pay. Until then, both they and other MetLife workers in similar jobs handling short-term disability claims were all paid hourly wages and overtime. Afterward, only the short-term disability specialists were paid by the hour and earned overtime.
