I got hired part-time a store a few days ago and my first day was yesterday. Today i got a call about a position i applied for a few weeks ago which is full time with way better pay. I'm 18 and this is my first job I've ever had. will leaving right away impact me future? should I? how to i explain it to my boss?
Let your current boss know that you are taking off for the full-time position. Say something nice to them on the way out.
Do NOT write anything in your resume that you worked there for a few days. You don't include a few days work on your resume unless you were literally saving the world during that time interval.
