Been with the company for a bit over 16 years. I started 2 years after it was founded. Lots of changes over the last 10 years and it's headed in a direction such that for the last couple years I'm not sure I want my name attached to it anymore. I have established myself as pretty much the gold standard of what I did there across the industry...problem is, I'm tired of doing it. I accepted a position in a department that doesn't yet exist at another, much bigger company...still in the automotive industry but effectively walking away from all that I'm the best at and starting something where there are already plenty of others in the industry that are better than me, doing a job sort of related but completely different than what I did previously. I got a text from new bossman on sunday that said "are you ready to give notice tomorrow?" We'd chatted a few times over the last year on the phone...I've known him for 15 years or so, and I was not ready for this to happen when it did. I was shaking so bad the rest of the day, didn't sleep that night, and could barely hit the keys on the keyboard the next morning when I drafted my resignation letter. I've calmed down considerably now and am starting to put together in my head what I'm gonna do when I get there, and the direction I want to take the new department that I guess its my job to figure out. Last time I changed jobs my only responsibility to come up with $300/month to give to my Dad for rent for my bedroom since I decided not to go to college. Now I have 2 houses worth of mortgage payments, a wife and a kid to support and keep happy. Nervous doesn't begin to describe it. But I hit "send" on monday, and that was that. No risk, no reward...right? I learned that instead of being a mostly angry asshole like most tell me I am, I'm an emotional little bitch sometimes...and that made me feel like even more of a little bitch. I'm over that now, and it's full speed sideways. I have a shitload to do at the old place, which really isn't my problem anymore but I still give a fuck so I'm at the very least, telling them what needs to change (like I've been telling them for years) to make the place run better in my absence, and actually extended my departure date to compensate for another guy who is out with medical issues for 3 times as long as he should be because he's a pussy. So much for my week off, but I had a hard time leaving them with nobody to cover for a week. For those who have made major changes in their jobs/careers...how long did it take to get over the initial shock?
