How does Brad Childress keep his job?

How does Brad Childress still have a job? He recently traded away a 3rd round pick for the troubled Randy Moss. Then one month later decided to waive him with out consulting the gm or owner. From the reports out of Minnesota of how Moss was acting, I do not blame him for wanting to waive Moss, but you need to work through the chain of command. You don't hold a press conference announcing you allowed Moss to say in New England to visit his family, then turn around and tell the team you released him. Another question is why did you sign him in the first place? Remeber Childress dealt with Terrell Owens while with the Eagles.Let's put the Moss issue aside. Childress is the same coach that cut wide out Marcus Robinson on Christmas Eve, this is the same coach who tried to fine Troy Williamson for missing time from the team for attending his grandmother funeral. Never mind how he has handled the Favre situation and throws his own players under a bus. Two weeks ago he went public against Favre for throw 3 picks in the Greeen Bay game. Last year he pointed blame on his full back Tahi for being the12th man in the huddle during the championship game. The year before he went public about possibly cutting punter Chris Kluwe for punting to Reggie Bush. Not to mention his in game coaching decisions, I have no idea how Brad Childress can still retain his job.
