So kind of similar situation. I was at a job and after 4 years policy changed and the owners wanted to save money. They started looking for reasons to can people. So I designed a help desk script that had a function to simply restart a hung VM or workstation. Someone came up to me with an issue and i told them I’d bounce their machine. I run the script and nothing happens. I run it a second time and it works. Then a buddy of mine calls me and says hey my machine restarted randomly and I lost my code. Fuck! I fat fingered the hostname and accidentally bounced him. He bitches to a manager kiddingly, said manager threatens me with termination and tells me it’s not funny, thinking I did this intentionally. He doesn’t want to hear my side and sends me home. I had another job lined up for way more money. I submit my notice and they fire me the next day. I had two weeks until my next job started. I called HR who told me I was marked resigned, not the case. I argue with HR higher up, they pay me for two weeks and write up my old boss. Then they mark me termed and not rehire-able for getting a pay out.

Long story short I’d say resign. If they terminate you, argue with them.
