A clerk who took a "micro-nap" nearly cost a German bank €222 million (£189m), according to The Times.
The blunder happened when the clerk's finger rested on the keyboard, upgrading a payment of €62.40 to the massive sum due for payment in to an unknown pensioner's account.
Although the error was discovered before appearing in the account the employee's direct supervisor failed to notice the multi-million euro mistake and was sacked.
However an employment tribunal has now found that she should only have received a warning and should not have lost her job.
The tribunal told the unnamed bank that, "this was indeed a terrible mistake but, considering all the circumstances, dismissal was not justified."
