It is against bank policy for an employee to be a POA on a customer's account (unless it is a family member). I feel there is a conflict of interest and a potential for liability upon the bank. The employee should not accept to be a POA for a customer. Just a couple of months ago, one of our customers asked our assistant cashier to be his POA, but she declined because she did not feel comfortable doing so plus our bank policy stated that she couldn't. I would proceed with caution.
