Nobody is getting any answers from Hackett until "the time is appropriate". Much like his CEO history with Steelcase. If you read his past and how he made Steelcase a profitable company you would have learned he is a Consolidator. He cut 12,000 jobs and closed half their plants. His goal was to reduce wasted space and unfortunately it's my belief he will do the same with Ford Motor Company.
Yes, he doesnt come from an automotive background but if you are cleaning up, cutting cost and eliminating non-maximized workspace you dont need to have that particular background.
The best thing we (employees) can do is save some money... update our resumes and wait for the announcement we know is coming. Good luck to you and I hope your plant survives...
