Is there a law mandating that all employment be listed? Omitting a high school fast food gig is accepted, why is omitting moonlighting not? It's not lying about education or employment, so I don't see how it is fraud.
Unfortunately, there is no clear cut rules about what constitutes resume fraud. Making up employment records is clearly a resume fraud. Omitting employment could be construed as fraud depending on the context. Omitting ice-cream parlor gig while in high school is probably OK. Working for Google and Facebook at the same time and omitting one might be not.
