I had an interview today, and the hiring manager laughed at the way GM does business. He said when you come to work for us, you work for us for life, unless you choose to leave on your own, or you really mess up and we need to let you go. We don't fire, we rotate IF there's only the slightest bit of slowdown, but we DO NOT let go of talent. AND, there is no shortage of slowdown. GM has a history opposite of this, and this coming from a former GM man. I am very much hoping I land this position, both for their integrity, their far superior position in the automotive world, as solely due to the respect of their comments.
The best thing you can do for those that are up and coming, is to become an advocate against GM, and tell the honest truth against this company. Be honest, let the stories prove the company to be worthwhile or not. If you accept a position with them, act as a mercenary for hire. Provide a skill set for a wage, but do not elevate beyond. Don't purchase their products and let time prove this correct or not.
If you want to change the culture, you have to have some principles yourself. I own five, well six non-GM vehicles, and I will never promote a GM vehicle to a friend or family member. Honestly if I was rich and could waste money, I would buy a GM product to beat it and burn it to the ground. That is my level of distaste.
I've worked within GM for many decades, yet I will never advocate for, because their culture is evil upon their employees. They treat their employees like dogs, and I've seen it well before Mary ever became a powerhouse within GM. You will find your place one side of the line in the sand. If you are experienced and opposed, it's because you put in the time and have witnessed the pain. If you are youthful and hopeful, your time will come to prove these statements true.
Vision, works two ways. Having the vision to see where you are going, and also having the vision to see the immovable roadblocks to avoid. I speculate that humanity only chooses to see where they want to go, and completely avoids the truths they choose not to see. This is GM.
