@Cobaltasaurus I've had that one happen, too. I left one night, schedule said one thing. (It was always posted on our register, couldn't avoid seeing it when we turned in our keys for the counter doors literally right on top of it.)
After I had left that night, they wrote in a change to the schedule that had me coming in six hours earlier.
No one called. No one said anything. So I come in when I was originally scheduled to come in, and oh, the screaming.
I ask when the change was made, and this conversation actually happens:
Me: "When did this get changed?"
Coworker: "Last night!"
Me: "After I left?"
Coworker: "Yeah!"
Me: "Did anybody try to contact me to let me know this?"
Coworker: "No, you're supposed to keep track of that yourself!"
Me: "How, exactly, when it's written in at midnight when the store is closed and no one informs me? Am I supposed to call in every morning?"
Coworker: "That's not my problem, and of course not! We shouldn't have to waste our time answering that!"
Me: "Did anyone try to call this morning when I wasn't here?"
Coworker: "No, why would we?"
Me: quietly "...I am so glad I am moving to a different state next week... "
Nobody saw a damn thing wrong with any of the above. Clearly, if this was never a problem for anyone before, the remainder of the staff had vastly superior psychic powers to my own.
Of course, were that actually the case, I suppose they would have known the place would end up closed in a few years due to consistent horrible mismanagement, which certainly didn't surprise me.
Shame, too. It was generally a really nice department store, and their fat lady clothes were less-than-typically depressing (but $$$, so the employee discount had been nice).
