<human>: I am a recently graduated librarian with a background mostly in customer service in retail and libraries. I'm trying to find my first "real" job and, although I know how to fill out applications and all that good stuff, I'm a little concerned that I've been doing it wrong (no interviews yet :(). My question is, do I really have to list ALL of my previous jobs on the application for a professional position? I know my resume can include only relevant work history but most apps ask for complete work history; I'm young, so I have things in my fairly recent past like Taco Bell and a movie theater that I usually leave off of applications, but I recently read something that said employers now have ways of electronically checking to see if work history is complete. I don't want them to think I'm lying; I just omit several of the part-time jobs I had when I was in my late teens, early twenties. I don't even remember the names of some of my managers at those jobs.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Will employers know or care if I leave part time jobs like "Taco Bell" and movie theater" off of my work history on an application that wants "complete work history"?
