Imagine, for a moment.
You are the former employee of a Fortune 50 company. Your employment ended six years ago.
Happily working at a new job, minding your own business, you suddenly find yourself in need of a US Government security clearance. Said clearance requires street addresses and phone numbers and contact names of all former places of employment, including verification address, job location, and supervisor name and address.
The actual location of your Fortune 50 job is no more. What do you put? What do you put for phone number? A non-existent number?
Your supervisor dropped off the face of the planet. You heard he might have moved to Montana to become a rancher. This story is anecdotal.
And as it happens, your former Fortune 50 company just merged with another huge company (Fortune 10? 20? Let's just say, the monopoly that was broken up in the 1980s seems to be back again). As in, a month ago. And closed the HR department. And the HR department for the monopoly doesn't have former other company employee information for verification purposes. And the outsourced company that handles the automated system for employment verification only has employee information back five years. And you end up calling the Office of the Executive Assistant to the President of the Monopoly asking for information and even she, although incredibly nice, had no information.
And if you don't fill out this information, you lose your job.
What would you do?
