This story is pretty tame by the standards of this sub, but I'm finding it pretty amusing.
I'm one of two people doing some design work that is scheduled to be refreshed every single week. We alternate weeks. So they have just enough staff to get this work done if no one ever gets sick, goes on vacation, or quits. And one of those two people (me) is a full-time freelancer who they only commit to a month or two of work at a time, about 2 weeks before the previous commitment ends. I've been doing this 6 months, and they have made it clear there is no staff position for me.
So, I found a new job. I gave them the courtesy of two weeks notice yesterday, making my last day the 20th of the month. I have only been asked to stay through the 27th anyway. So I told them I'm leaving 5 working days earlier than they have committed to me.
Well, project managers were shocked, staff were scared of the impending workload, they had to call the boss while he's on vacation to discuss staffing coverage. They are panicked figuring out what to do.
It's fun watching the fireworks, honestly.
