Should this question on getting fired on the last day be marked off topic?
Actually it was marked "primarily opinion-based" because it asked in part for speculation on the state of mind of the employer, which is unknowable.
Also the number of potential answers, as to why someone might be fired on their last day, is infinite.
One hundred users could respond in 100 different ways, and each answer could be equally correct.
The reason questions like this get closed is to prevent the other 97 users from answering.
We (like other SE sites) are looking for questions with a few potential answers that people can agree upon.
If there's a way to rewrite this so it can be answered more objectively, then I think people would be more likely to reopen.
There are some pretty good answers in there already, however.
