German luxury carmaker Audi's management board, including Chief Executive Rupert Stadler, has been sharply criticised by company managers, Bild am Sonntag reported on Sunday, citing an internal dossier. It said the executive board had shown no signals of a fresh start, change or readiness for the future, and that workers were frustrated with "disastrous" indecisiveness. Stadler has come under fire for how he has handled the fallout from parent company Volkswagen's diesel emissions scandal.
