Ethical or not, I'd be more concerned about what I'd do if the current job ended, regardless of why it ended. What do you tell the company you're interviewing with about what you did at your last job? And I don't mean discussing this with them, I mean what do you say about the projects you worked on over the past n years when there's only this one automation?
