I know from working in AIB (a long time ago) that staff are expected to be holyier than thou when it comes to their finances. That might have changed but when i was there if you were in money trouble of any level, a quiet word was given by your manager. It's like a guard having points on his license. It doesn't look good for the company. But after what we all read lately about their mad loans to themselves (nice to see they were not immune from silly borrowing) I would not bet my last euro on them getting their redundancy scot free if they owe big money on non performing loans.
A guy I know had a business that was sinking slowly years ago. He had two premises. Sold one. Didn't put the proceeds into his current account for the very reason the other building had a large loan that was struggling. The bank actually rang him to express their shall we say 'upset' about what he had done.
If the bank sees a solution especially in this climate to recoup money, I would expect them to jump at it. Certainly if it's one of their own staff and they are the go between the persons money and redundancy
