> It is the former employees for up to 15 years that make the contacting step difficult. They all need to provide bank/tax details.
Give people 30 dollars extra on their way out, and only contact them when you used up that budget? (Should take care of the majority of cases?)
> Edit: I should have said, I did see companies rounding all amounts up to some small amount, like $1, so your suggestion is good. It just doesn't save effort on recalculation, or much effort in getting people to dig the email out of their trash folder and provide their information to receive their $1.
Oh, my suggestion was to do the calculation, as arduously as you describe, compare with what you already overpaid earlier voluntarily, and if the company is still in the green, then don't bother contacting anyone.
Or is that not possible?
