Dumbest email ever?

Some 1,300 employees at a British company received an email Friday saying they'd been sacked.

The memo certainly sounded official. The workers at Aviva, Britain's second-largest insurance company, were told they had been fired and that company property must be returned. The mail went on to say: "I am required to remind you of your contractual obligations to the company you are leaving. You have an obligation to retain any confidential information pertaining to Aviva Investors operations, systems and clients."

According to the Huffington Post, the email was actually only intended for one person. "One really, really unfortunate person."

As an Aviva spokesman explained, "It was intended that this e-mail should have gone to one single person. Unfortunately, as a result of a clerical error, it was sent to all of the Investors staff worldwide.”

The company sent a second mass email, described as "grovelling" by one media outlet, apologizing for the mistake. "Workers who remain employed will no doubt derive comfort from knowing if they ever face the chop it will be done by email."

How many ways is this thing all wrong?

New management welcome.
