I work as a backup bookkeeper currently, and my employer has known the entire time that I've been hoping to either a.) go to graduate school, or b.) apply for a position in the company at a different location. Thankfully, all of my managers are very pro education and I've had a ton of support in the process. I worked there during my undergrad as well, and when I took an internship my final semester, I was allowed to step down without losing pay and work 1 day a week. When I graduated, they re-promoted me and I got more hours. I'm thankful that I didn't have to keep my goals a secret and that I was supported and encouraged, even though it means leaving the company (there are no locations to transfer to where my program is).
