A financial controller for Ford Motor Company's Greenleaf LLC recycling subsidiary has filed a 'whistleblower' lawsuit against the company, claiming she was sacked after raising questions about company accounting practices, the Detroit News reported. Andrea Poppe-Grove, a manager for Greenleaf, a chain of 31 scrapyard and recycling centres in 14 US states, filed the civil claim in Wayne County Circuit Court last month, the newspaper said.
