Having left Atos in November, I'd offer an alternative view.If you're smart, capable, and have the ability to deliver, both you and management realise you would do better elsewhere, so you look elsewhere, and leverage that offer into an internal promotion to move up the 9 (count 'em) consulting ranks within Atos.Not always the best move for bridges, but it has worked for quite a few people who have moved up quickly within Atos and then subsequently left within 3 months of their promotion.The bi-annual bonus makes it less financially painful to leave at any point in the year.
