If there was an active shooter in the building and the email was “yo, I’m leaving for the rest of day and not coming back until I have more info on the active shooter situation” does the corporation have any option other than to immediately terminate that employee?

In that situation, the employee is saying they will do something that the employer likely wants them to do, or is at most indifferent to. It would be more similar to someone sending an e-mail to their boss saying 'I am coming in to work on Monday, and planning to work very hard, because I fully support the management'.

Yes, they have the option of providing more info on the active shooter situation.
