Can an employee background check discover a unmentioned previous employer?
I was laid-off "due to downsizing" from a company in which I was employed 11 mos. It was a customer service job in which I hated and I'd like to leave it off my resume in general. If an employer performs a background check, can they discover I once worked for a company and failed to mentioned it?
no a background check is for illegal stuff Doubtful.
But how will you explain the gap in your resume?
Background checks vary from company to company, but generally they include calling all companies listed on your application and verifying title, dates of employment, wage & eligibility for rehire. Also, depending on company, the background check may include criminal, credit checks and education verification.
The only way a company could get that info would be if one of their current employees knows you, and knows about the job or if they require you to submit tax returns with documentation. Unless you are in high level sales it is doubtful they would ever ask for that. Possibly. If you were laid off due to downsizing, why do you feel you don't want to mention it on your resume and applicaiion? List it - there's no shame in getting laid off. It's better than showing an 11 month gap on your resume.
