Hi guys, This is my first time posting on SDN so I hope that I don't offend or irritate anyone. So, I'm having a pretty rough application cycle and a rough year in general and my part-time research position is not helping the situation. My supervisor is absolutely unprofessional and mean and some of my co-workers are pretty bad as well. Anyway, I was offered a much more interesting research position and the PI of this new project seems more receptive to my needs. Now I am faced with the dilemma of quitting my current job which I absolutely loathe. But, I am really worried b/c the PI is a faculty member of my top choice school. I know that I will not get a LoR or an abstract/publication out of this job. The PI for the new opportunity is also a faculty member of my top choice school and I know that if I work hard, I will get a LoR and an abstract/publication out of this new opportunity. All constructive feedback will be really appreciated. EDIT: Do I need to inform the schools I applied to that I left the job I wrote on my secondaries and that I have a new research position? Will it look bad to leave this job if I just started it in October?
