I know of at least 2 in H/M that did not recieve pin numbers.
1 had only just been payed as a lame so the payroll staff numbers missed him
The other has been a lame for years and was a vocal one at meetings.
Local H.R did not know a thing about the vote.
It involved having to do things like contact your manager and get him to contact IR so they could inform elecions australia.
The whole system was a shamble.
What would happen if you were on leave for a couple of weeks and didn't realise that you didn't get a pin?
