I listened to a radio feature on the post office fiasco a couple of years ago. From what I remember, this woman forced a computer program (Horizon?) onto the post office despite it not being fit for purpose. Prosecutions for theft were taken out on behalf of the post office against their own staff because the end of day totals didn’t tally. No thought was given that the computer system could have been wrong.
Post office staff ended up being wrongly jailed, wrongly getting a criminal record, losing their jobs, losing their businesses, and some of them even tragically couldn’t cope and took their own lives. All because of the decisions by this stupid woman who really should be in the dock.
