How do I quit my job the RIGHT way?

[blah_blah_blah]

Hello AN!

I was interviewed and hired today by a facility that I spent over a year trying to get into.

I currently have 3 jobs, I work FT at an office, per diem at a hospital, and I am a sub school nurse.

I know how I'm going to quit my office job and I plan on keeping my school job.

I don't know how to go about quitting my hospital job. I'm per diem so I'm not in a lot. I haven't worked a shift there in at least a month. I feel bad because I really don't enjoy the work there and they call me all the time looking for me to take/fill shifts and I never really return their calls so I'm scared it may be awkward. Like "hey I never call you back or answer the phone when you call me, but I'm putting in my notice." I really like my coworkers and manager, I just dislike the specialty.

Should I stop in and talk to my manager? Do I call her and tell her on the phone? Just send in a letter of resignation? Thanks!

It's per diem, simply stop accepting shifts.....
