I recently retired from DTE after32 years and have nothing but good to say about them (at least the gas side of the company Michcon)).
They have a no lay-off policy and do everything to avoid any type of lay off. They plan ahead the best they can and offer generous buyouts and rely on attrition and will relocate employees as needed. They work very reasonably with their employees in personal time of need and offer any help they possibly can. Whoever disputes this must not be a reasonable employee. By the way, I was a represented employee and can tell you they work well with the unions.
