A Delaware judge has dismissed claims against directors of McDonald’s in a shareholder lawsuit challenging their handling of sexual harassment by former CEO Steve Easterbrook and the company’s former top human resources executive.

Former McDonald’s workers who alleged rampant sexual harassment at their Michigan restaurant have reached a $1.5 million settlement agreement with the restaurant’s former owner.

For all the potential peril of a workplace romance, the most common source of trouble, experts say, is allowing it to remain a secret.

Former McDonald’s CEO Steve Easterbrook has paid back more than $105 million in equity awards and cash to the burger giant after it learned that he had lied about the extent of his misconduct while he was its top executive.

McDonald’s will mandate worker training to combat harassment, discrimination and violence in its restaurants worldwide starting next year.

An internal investigation by McDonalds of potential misconduct has extended beyond its former CEO who was forced out late last year. After Easterbrook was became McDonald's CEO in 2015 he named Fairhurst, a friend, to lead the human resource department. Yet in July, McDonalds received information from another company employee suggesting that Easterbrook had multiple affairs with subordinates. The same person also told the company about issues within the human resources department. McDonalds named Heidi Capozzi, who had worked for Boeing, as human resources chief in March.
