they said target debit gave info to headquarters and they transferred it to the store. it just seems odd to be able to fire a worker for getting overdraft charges on a debit card, because i paid target and owe nothing anymore, to me seems like wrongful termination if they did not give us any info about what can happen.
Don't panic about your Redcard issues. I'm sure that you'll be OK for the time being. I would guess that you'd have to REALLY have to have some serious issues with the Redcard before you'd be terminated.
Also, if you have a debit card, any money issues would be with your bank, not Target.
The debit card is not a debit card so much as it is a check card. When you make a purchase using it, it takes a couple of days to clear, just like a check. If Target tries to get their money (like they would a regular check) and the money isn't there, boom, overdraft. So, no, the money issues are with Target for wanting their money for the original purchase and the overdraft fee and with your bank for the overdraft from them as well.
When I had no money in my account, I would use my RedCard to buy my essentials at Target because it would go through no matter how negative my account was. Of course I racked up overdraft charges for every time I swiped it and didn't have the funds, but it always got paid back when my check hit my account.
Nobody ever said anything to me about it, but I would never have been surprised if they did. I don't really know what the policy on that is but I've never heard of anyone being termed over it. I have heard of people being talked to (not at my store, but elsewhere) for failing to pay the balance on their Target credit card, but never heard of anything about overdrafting with the debit. Like @pellinore said, have your HR show you where that information is written. I'm kind of curious to know how they get that kind of info as well.
