The funny thing is that I didn't intend to tell them yesterday - I was planning on doing it on Friday because I have been nervous about how to broach the subject with them. And in the end, when they asked me, pointe-blanc if something is wrong, I figured I owed them the truth. I told them how disappointed I was with the role not being anything like they promised - I'm a Chartered Accountant not a personal assistant or secretary. I said that I've reached a point in my life where I expect more from my job on all levels. The senior manager tried to see if there was anything she could do to make me change my mind but I said no. Or rather I gave them some conditions which I knew they wouldn't be able to promise (which were basically what I was promised when I took the job) and they accepted it. I was surprised because the senior manager actually seemed to understand and just apologized to me about how unfairly I've been treated - which I wasn't expecting. The other manager though, I think, is just pissed at me.
Anyway, long story short, I'm just glad its over. I'm going to hand in my resignation letter tomorrow to make it official. October 14th will be my last day.
