Replyallpocalypse

Hitting "reply all" on a mass email is generally a bad idea, but a meltdown at the UK’s National Health Service (NHS) is the worst reply allpocalypse we’ve ever seen. According to The Guardian, more than 186 million useless emails were sent out, after a technician sent a "test" message to all 1.2 million employees of the NHS.

We’ve now had 20 years of cautionary tales about replyallpocalypses. For the sake of workplace harmony: keep your pointer off the nuclear button.
