I agree with that yes - if your employer resolves the situation quickly without causing you stress that's fair. However - it's their obligation, above all else, to make sure you're getting paid. If this sort of error occurs repeatedly due to someone unqualified to handle the books then your employer should rectify the situation. I think it's fair - while that money is tied up in limbo - to essentially cease working. That provides a very clear incentive and attaches a level of importance to the incident that should prompt your employer to correct in the future. Everyone makes mistakes - we're all human - however recovering denied wages is a very difficult legal fight that often results in failure due to debt shenanigans and the like. As an employee you need to be incredibly defensive about any interruption to your pay stream.
