I applied for a job after I was laid off from my old position as a system admin. I was not offered a full-time job, but I was offered an internship with the caveat that I would go back to school and complete my B.S. degree in the fall.
I only have a two year degree right now and I never really wanted to get my B.S, but knew I really wanted to work full-time again so I took the internship while looking for another job. I've finally gotten a full-time offer that does not require me to go back to school.
How do I handle telling my boss I'm leaving the intern position while still being professional?
