I was working at Vanguard, about to get a promotion I didn't want, 27, single, nothing holding me in one spot so I quit and moved to Europe for a year.
So you worked at Vanguard and loved it (based on previous posts) -- what sort of promotion would drive you to quit? Couldn't you have politely declined?
I was being promoted to a paper pusher. Not a bad job but one that would have driven me insane with boredom. I was working in the AZ office and they do not have all of the jobs there that you could get at headquarters. I was as far as I was going to get and still have a job I was interested in. The job I was in at the time had pretty much been created specifically for me and I was allowed to make it into what I wanted it to be. The advantage was that it was very interesting and challenging while I was doing the creating. The disadvantage was that once I got all the kinks straightened out it was neither interesting nor challenging, it was just time management. That was the situation I was in when offered the promotion. My ideal job would have been with the education department, traveling to clients and teaching them about their 401k plans, but that wasn't an option.
I'm a trouble shooter/problem solver and I get bored quickly and easily which is why I like consulting and project work. Doing the same thing day after day is my version of hell.
So, while Vanguard is an excellent company, it is still a corporation that has rules about what people in specific positions can and can't do and that doesn't fit my work-personality very well. I would have stayed there forever if they had allowed me to just hop from department to department solving problems along the way.
