Today I was supposed to work. A coworker agreed to cover my shift and we emailed the request to HR yesterday. I went to bed happy last night. Woke up happy today.

Then, 15 minutes before the start of that shift, I get a text from the coworker saying she'd emailed HR to cancel the request. No big emergency. She just changed her mind cause she had some last-minute brunch or some silly **** like that.

"sorry, hope you understand" is the last thing she writes.

Yes, I understand that you totally threw me under the bus. I hope YOU'll understand that I'm throwing you back under it with this email I just wrote to HR and CC'ed you on.

Enjoy your brunch.
