Sounded to me like the company did the checks on their own.
The origional rules whenever you filed a payroll report they notifired you to correct it or be fined.
There was no way for an employer to make the check themselves.
We got a couple of them over the years from employees transposing numbers on their W-2 which only took a letter to clear it up.
All i’m saying is that the goovwrnment should adhear ro the rule of notifying the employer every time that there is a discrepancy and follow it up with the action the law calls for, firing or fine.
Nothing random, every occurance!
