This is a slightly older story, but thinking back on it, it seems very appropriate for this sub.
I'd had an uncle pass away while I was working in a call center, and so I went through the company's process of requesting leave for bereavement (unpaid). I only requested 1 day off, so that I could attend the funeral.
Days go by without any update on the status of my request. I asked both my manager and my supervisor, but they told me I would have an answer by the date in question.
The morning of, I still have no answer, so I say fuck it and just go. Standing there, surrounded by family and friends crying, they decide its appropriate to start blowing up my phone demanding to know why I never showed up or even called in.
Never have I quit a job so fucking fast. Good to see (a few years later) that they'd closed down.
Here's a retroactive fuck you for any employer who's pulled that kind of shit.
