Since the vertical lines of authority are narrow this means people tend to agree only with their bosses and their boss's boss and try to kick and gouge everyone else. There is no way to fight the Microsoft culture. It is either adapt or leave. Adapting means coming to understand that Microsoft is all about e-mail and not answering those 400 stupid messages is a sin. Survival means becoming a drone, so all your attention goes into quality of life.
People start coming to work later and leaving earlier.
It's no longer about the business plan, but Microsoft is making so much money that nobody even notices.
