'15 other people saw it': Karen sends unkind message about coworker to entire department by accident, coworker reports her to HR

Always be careful who you're sending your messages to, especially at work! One would think this is a self-explanatory warning and not something that needs to be stated, but it turns out some coworkers out there really are that reckless. 

Here, we have a Karen coworker who liked to boss others around, especially this Redditor who was fully on her level within the hierarchy of their company. Karen told her to take lunch at 11 am, but something came up and OP switched lunch times with another employee. This did not affect Karen's schedule in any way, yet she felt the need to gossip about it. However, instead of messaging her work bestie, she messaged the entire department. Sure, she quickly deleted the message but not until everyone in the group already saw it. Let's hope that OP follows through with HR proceedings because this was apparently not the first time this Karen was difficult with other coworkers.
